 # The user-driven targets are:
 #
 # universe            - *Really* build *everything* (buildworld and
 #                       all kernels on all architectures).
 # tinderbox           - Same as universe, but presents a list of failed build
 #                       targets and exits with an error if there were any.
 # buildworld          - Rebuild *everything*, including glue to help do
 #                       upgrades.
 # installworld        - Install everything built by "buildworld".
 # world               - buildworld + installworld, no kernel.
 # buildkernel         - Rebuild the kernel and the kernel-modules.
 # installkernel       - Install the kernel and the kernel-modules.
 # installkernel.debug
 # reinstallkernel     - Reinstall the kernel and the kernel-modules.
 # reinstallkernel.debug
 # kernel              - buildkernel + installkernel.
 # kernel-toolchain    - Builds the subset of world necessary to build a kernel
 # kernel-toolchains   - Build kernel-toolchain for all universe targets.
 # doxygen             - Build API documentation of the kernel, needs doxygen.
 # update              - Convenient way to update your source tree(s).
 # checkworld          - Run test suite on installed world.
 # check-old           - List obsolete directories/files/libraries.
 # check-old-dirs      - List obsolete directories.
 # check-old-files     - List obsolete files.
 # check-old-libs      - List obsolete libraries.
 # delete-old          - Delete obsolete directories/files.
 # delete-old-dirs     - Delete obsolete directories.
 # delete-old-files    - Delete obsolete files.
 # delete-old-libs     - Delete obsolete libraries.
 # targets             - Print a list of supported TARGET/TARGET_ARCH pairs
 #                       for world and kernel targets.
 # toolchains          - Build a toolchain for all world and kernel targets.
 # xdev                - xdev-build + xdev-install for the architecture
 #                       specified with TARGET and TARGET_ARCH.
 # xdev-build          - Build cross-development tools.
 # xdev-install        - Install cross-development tools.
 # xdev-links          - Create traditional links in /usr/bin for cc, etc
 # native-xtools       - Create host binaries that produce target objects
 #                       for use in qemu user-mode jails.  TARGET and
 #                       TARGET_ARCH should be defined.
 # native-xtools-install
 #                     - Install the files to the given DESTDIR/NXTP where
 #                       NXTP defaults to /nxb-bin.
 # 
 # "quick" way to test all kernel builds:
 # 	_jflag=`sysctl -n hw.ncpu`
 # 	_jflag=$(($_jflag * 2))
 # 	[ $_jflag -gt 12 ] && _jflag=12
 # 	make universe -DMAKE_JUST_KERNELS JFLAG=-j${_jflag}
 #
 # This makefile is simple by design. The FreeBSD make automatically reads
 # the /usr/share/mk/sys.mk unless the -m argument is specified on the
 # command line. By keeping this makefile simple, it doesn't matter too
 # much how different the installed mk files are from those in the source
 # tree. This makefile executes a child make process, forcing it to use
 # the mk files from the source tree which are supposed to DTRT.
 #
 # Most of the user-driven targets (as listed above) are implemented in
 # Makefile.inc1.  The exceptions are universe, tinderbox and targets.
 #
 # If you want to build your system from source be sure that /usr/obj has
 # at least 6GB of diskspace available.  A complete 'universe' build requires
 # about 100GB of space.
 #
 # For individuals wanting to build from the sources currently on their
 # system, the simple instructions are:
 #
 # 1.  `cd /usr/src'  (or to the directory containing your source tree).
 # 2.  Define `HISTORICAL_MAKE_WORLD' variable (see README).
 # 3.  `make world'
 #
 # For individuals wanting to upgrade their sources (even if only a
 # delta of a few days):
 #
 #  1.  `cd /usr/src'       (or to the directory containing your source tree).
 #  2.  `make buildworld'
 #  3.  `make buildkernel KERNCONF=YOUR_KERNEL_HERE'     (default is GENERIC).
 #  4.  `make installkernel KERNCONF=YOUR_KERNEL_HERE'   (default is GENERIC).
 #       [steps 3. & 4. can be combined by using the "kernel" target]
 #  5.  `reboot'        (in single user mode: boot -s from the loader prompt).
 #  6.  `mergemaster -p'
 #  7.  `make installworld'
 #  8.  `mergemaster'		(you may wish to use -i, along with -U or -F).
 #  9.  `make delete-old'
 # 10.  `reboot'
 # 11.  `make delete-old-libs' (in case no 3rd party program uses them anymore)
 #
 # See src/UPDATING `COMMON ITEMS' for more complete information.
 #
 # If TARGET=machine (e.g. powerpc, sparc64, ...) is specified you can
 # cross build world for other machine types using the buildworld target,
 # and once the world is built you can cross build a kernel using the
 # buildkernel target.
 #
 # Define the user-driven targets. These are listed here in alphabetical
 # order, but that's not important.
 #
 # Targets that begin with underscore are internal targets intended for
 # developer convenience only.  They are intentionally not documented and
 # completely subject to change without notice.
 #
 # For more information, see the build(7) manual page.
 #
 
 # This is included so CC is set to ccache for -V, and COMPILER_TYPE/VERSION
 # can be cached for sub-makes.

 # Building a world goes through the following stages
 #
 # 1. legacy stage [BMAKE]
 #	This stage is responsible for creating compatibility
 #	shims that are needed by the bootstrap-tools,
 #	build-tools and cross-tools stages. These are generally
 #	APIs that tools from one of those three stages need to
 #	build that aren't present on the host.
 # 1. bootstrap-tools stage [BMAKE]
 #	This stage is responsible for creating programs that
 #	are needed for backward compatibility reasons. They
 #	are not built as cross-tools.
 # 2. build-tools stage [TMAKE]
 #	This stage is responsible for creating the object
 #	tree and building any tools that are needed during
 #	the build process. Some programs are listed during
 #	this phase because they build binaries to generate
 #	files needed to build these programs. This stage also
 #	builds the 'build-tools' target rather than 'all'.
 # 3. cross-tools stage [XMAKE]
 #	This stage is responsible for creating any tools that
 #	are needed for building the system. A cross-compiler is one
 #	of them. This differs from build tools in two ways:
 #	1. the 'all' target is built rather than 'build-tools'
 #	2. these tools are installed into TMPPATH for stage 4.
 # 4. world stage [WMAKE]
 #	This stage actually builds the world.
 # 5. install stage (optional) [IMAKE]
 #	This stage installs a previously built world.

 # In the following, the first 'rm' in a series will usually remove all
 # files and directories.  If it does not, then there are probably some
 # files with file flags set, so this unsets them and tries the 'rm' a
 # second time.  There are situations where this target will be cleaning
 # some directories via more than one method, but that duplication is
 # needed to correctly handle all the possible situations.  Removing all
 # files without file flags set in the first 'rm' instance saves time,
 # because 'chflags' will need to operate on fewer files afterwards.
 #
 # It is expected that BW_CANONICALOBJDIR == the CANONICALOBJDIR as would be
 # created by bsd.obj.mk, except that we don't want to .include that file
 # in this makefile.  We don't do a cleandir walk if MK_AUTO_OBJ is yes

 .Os
 .Sh NAME
 .Nm build
 .Nd information on how to build the system
 .Sh DESCRIPTION
 The sources for the
 .Fx
 system and its applications are contained in three different directories,
 normally
 .Pa /usr/src ,
 .Pa /usr/doc ,
 and
 .Pa /usr/ports .
 These directories may be initially empty or non-existent until updated with
 .Xr svn 1
 or
 .Xr portsnap 8 .
 Directory
 .Pa /usr/src
 contains the
 .Dq "base system"
 sources, which is loosely defined as the things required to rebuild
 the system to a useful state.
 Directory
 .Pa /usr/doc
 contains the source for the system documentation, excluding the manual
 pages.
 Directory
 .Pa /usr/ports
 contains a tree that provides a consistent interface for building and
 installing third party applications.
 For more information about the ports build process, see
 .Xr ports 7 .
 .Pp
 The
 .Xr make 1
 command is used in each of these directories to build and install the
 things in that directory.
 Issuing the
 .Xr make 1
 command in any directory or
 subdirectory of those directories has the same effect as issuing the
 same command in all subdirectories of that directory.
 With no target specified, the things in that directory are just built.
 .Pp
 A source tree is allowed to be read-only.
 As described in
 .Xr make 1 ,
 objects are usually built in a separate object directory hierarchy
 specified by the environment variable
 .Va MAKEOBJDIRPREFIX ,
 or under
 .Pa /usr/obj
 if variable
 .Va MAKEOBJDIRPREFIX
 is not set.
 The canonical object directory is described in the documentation for the
 .Cm buildworld
 target below.
 .Pp
 The build may be controlled by defining
 .Xr make 1
 variables described in the
 .Sx ENVIRONMENT
 section below, and by the variables documented in
 .Xr make.conf 5 .
 .Pp
 The following list provides the names and actions for the targets
 supported by the build system:
 .Bl -tag -width ".Cm cleandepend"
 .It Cm analyze
 Run Clang static analyzer against all objects and present output on stdout.
 .It Cm check
 Run tests for a given subdirectory.
 The default directory used is
 .Pa ${.OBJDIR} ,
 but the check directory can be changed with
 .Pa ${CHECKDIR} .
 .It Cm checkworld
 Run the
 .Fx
 test suite on installed world.
 .It Cm clean
 Remove any files created during the build process.
 .It Cm cleandepend
 Remove the
 .Pa ${.OBJDIR}/${DEPENDFILE}*
 files generated by prior
 .Dq Li "make"
 and
 .Dq Li "make depend"
 steps.
 .It Cm cleandir
 Remove the canonical object directory if it exists, or perform
 actions equivalent to
 .Dq Li "make clean cleandepend"
 if it does not.
 This target will also remove an
 .Pa obj
 link in
 .Pa ${.CURDIR}
 if that exists.
 .Pp
 It is advisable to run
 .Dq Li "make cleandir"
 twice: the first invocation will remove the canonical object directory
 and the second one will clean up
 .Pa ${.CURDIR} .
 .It Cm depend
 Generate a list of build dependencies in file
 .Pa ${.OBJDIR}/${DEPENDFILE} .
 Per-object dependencies are generated at build time and stored in
 .Pa ${.OBJDIR}/${DEPENDFILE}.${OBJ} .
 .It Cm install
 Install the results of the build to the appropriate location in the
 installation directory hierarchy specified in variable
 .Va DESTDIR .
 .It Cm obj
 Create the canonical object directory associated with the current
 directory.
 .It Cm objlink
 Create a symbolic link to the canonical object directory in
 .Pa ${.CURDIR} .
 .It Cm tags
 Generate a tags file using the program specified in the
 .Xr make 1
 variable
 .Va CTAGS .
 The build system supports
 .Xr ctags 1
 and
 .Nm "GNU Global" .
 .El
 .Pp
 The other supported targets under directory
 .Pa /usr/src
 are:
 .Bl -tag -width ".Cm distributeworld"
 .It Cm buildenv
 Spawn an interactive shell with environment variables set up for
 cross-building the system.
 The target architecture needs to be specified with
 .Xr make 1
 variables
 .Va TARGET_ARCH
 and
 .Va TARGET .
 .Pp
 This target is only useful after a complete cross-toolchain including
 the compiler, linker, assembler, headers and libraries has been
 built; see the
 .Cm toolchain
 target below.
 .It Cm buildworld
 Build everything but the kernel, configure files in
 .Pa etc ,
 and
 .Pa release .
 The object directory can be changed from the default
 .Pa /usr/obj
 by setting the
 .Pa MAKEOBJDIRPREFIX
 .Xr make 1
 variable.
 The actual build location prefix used
 depends on the
 .Va WITH_UNIFIED_OBJDIR
 option from
 .Xr src.conf 5 .
 If enabled it is
 .Pa ${MAKEOBJDIRPREFIX}${.CURDIR}/${TARGET}.${TARGET_ARCH}
 for all builds.
 If disabled it is
 .Pa ${MAKEOBJDIRPREFIX}${.CURDIR}
 for native builds, and
 .Pa ${MAKEOBJDIRPREFIX}/${TARGET}.${TARGET_ARCH}${.CURDIR}
 for cross builds and native builds with variable
 .Va CROSS_BUILD_TESTING
 set.
 .It Cm cleanworld
 Attempt to clean up targets built by a preceding
-.Cm buildworld
-step.
+.Cm buildworld ,
+or similar step built from this source directory.
+.It Cm cleanuniverse
+When
+.Va WITH_UNIFIED_OBJDIR
+is enabled, attempt to clean up targets built by a preceding
+.Cm buildworld ,
+.Cm universe ,
+or similar step, for any architecture built from this source directory.
 .It Cm distributeworld
 Distribute everything compiled by a preceding
 .Cm buildworld
 step.
 Files are placed in the directory hierarchy specified by
 .Xr make 1
 variable
 .Va DISTDIR .
 This target is used while building a release; see
 .Xr release 7 .
 .It Cm native-xtools
 This target builds a cross-toolchain for the given
 .Sy TARGET
 and
 .Sy TARGET_ARCH ,
 as well as a select list of static userland tools for the host system.
 This is intended to be used in a jail where QEMU is used to improve
 performance by avoiding emulating binaries that do not need to be emulated.
 .Sy TARGET
 and
 .Sy TARGET_ARCH
 should be defined.
 .It Cm native-xtools-install
 Installs the results to
 .Pa ${DESTDIR}/${NXTP}
 where
 .Va NXTP
 defaults to
 .Pa nxb-bin .
 .Sy TARGET
 and
 .Sy TARGET_ARCH
 must be defined.
 .It Cm packageworld
 Archive the results of
 .Cm distributeworld ,
 placing the results in
 .Va DISTDIR .
 This target is used while building a release; see
 .Xr release 7 .
 .It Cm installworld
 Install everything built by a preceding
 .Cm buildworld
 step into the directory hierarchy pointed to by
 .Xr make 1
 variable
 .Va DESTDIR .
 .Pp
 If installing onto an NFS file system and running
 .Xr make 1
 with the
 .Fl j
 option, make sure that
 .Xr rpc.lockd 8
 is running on both client and server.
 See
 .Xr rc.conf 5
 on how to make it start at boot time.
 .It Cm toolchain
 Create the build toolchain needed to build the rest of the system.
 For cross-architecture builds, this step creates a cross-toolchain.
 .It Cm universe
 For each architecture,
 execute a
 .Cm buildworld
 followed by a
 .Cm buildkernel
 for all kernels for that architecture,
 including
 .Pa LINT .
 This command takes a long time.
 .It Cm update
 Get updated sources as configured in
 .Xr make.conf 5 .
 .It Cm targets
 Print a list of supported
 .Va TARGET
 /
 .Va TARGET_ARCH
 pairs for world and kernel targets.
 .It Cm tinderbox
 Execute the same targets as
 .Cm universe .
 In addition print a summary of all failed targets at the end and
 exit with an error if there were any.
 .It Cm toolchains
 Create a build toolchain for each architecture supported by the build system.
 .It Cm xdev
 Builds and installs a cross-toolchain and sysroot for the given
 .Sy TARGET
 and
 .Sy TARGET_ARCH .
 The sysroot contains target library and headers.
 The target is an alias for
 .Cm xdev-build
 and
 .Cm xdev-install .
 The location of the files installed can be controlled with
 .Va DESTDIR .
 The target location in
 .Va DESTDIR
 is
 .Pa ${DESTDIR}/${XDTP}
 where
 .Va XDTP
 defaults to
 .Pa /usr/${XDDIR}
 and
 .Va XDDIR
 defaults to
 .Pa ${TARGET_ARCH}-freebsd .
 .It Cm xdev-build
 Builds for the
 .Cm xdev
 target.
 .It Cm xdev-install
 Installs the files for the
 .Cm xdev
 target.
 .It Cm xdev-links
 Installs autoconf-style symlinks to
 .Pa ${DESTDIR}/usr/bin
 pointing into the xdev toolchain in
 .Pa ${DESTDIR}/${XDTP} .
 .El
 .Pp
 Kernel specific build targets in
 .Pa /usr/src
 are:
 .Bl -tag -width ".Cm distributekernel"
 .It Cm buildkernel
 Rebuild the kernel and the kernel modules.
 The object directory can be changed from the default
 .Pa /usr/obj
 by setting the
 .Pa MAKEOBJDIRPREFIX
 .Xr make 1
 variable.
 .It Cm installkernel
 Install the kernel and the kernel modules to directory
 .Pa ${DESTDIR}/boot/kernel ,
 renaming any pre-existing directory with this name to
 .Pa kernel.old
 if it contained the currently running kernel.
 The target directory under
 .Pa ${DESTDIR}
 may be modified using the
 .Va INSTKERNNAME
 and
 .Va KODIR
 .Xr make 1
 variables.
 .It Cm distributekernel
 Install the kernel to the directory
 .Pa ${DISTDIR}/kernel/boot/kernel .
 This target is used while building a release; see
 .Xr release 7 .
 .It Cm packagekernel
 Archive the results of
 .Cm distributekernel ,
 placing the results in
 .Va DISTDIR .
 This target is used while building a release; see
 .Xr release 7 .
 .It Cm kernel
 Equivalent to
 .Cm buildkernel
 followed by
 .Cm installkernel
 .It Cm kernel-toolchain
 Rebuild the tools needed for kernel compilation.
 Use this if you did not do a
 .Cm buildworld
 first.
 .It Cm reinstallkernel
 Reinstall the kernel and the kernel modules, overwriting the contents
 of the target directory.
 As with the
 .Cm installkernel
 target, the target directory can be specified using the
 .Xr make 1
 variable
 .Va INSTKERNNAME .
 .El
 .Pp
 Convenience targets for cleaning up the install destination directory
 denoted by variable
 .Va DESTDIR
 include:
 .Bl -tag -width ".Cm delete-old-libs"
 .It Cm check-old
 Print a list of old files and directories in the system.
 .It Cm delete-old
 Delete obsolete base system files and directories interactively.
 When
 .Li -DBATCH_DELETE_OLD_FILES
 is specified at the command line, the delete operation will be
 non-interactive.
 The variables
 .Va DESTDIR ,
 .Va TARGET_ARCH
 and
 .Va TARGET
 should be set as with
 .Dq Li "make installworld" .
 .It Cm delete-old-libs
 Delete obsolete base system libraries interactively.
 This target should only be used if no third party software uses these
 libraries.
 When
 .Li -DBATCH_DELETE_OLD_FILES
 is specified at the command line, the delete operation will be
 non-interactive.
 The variables
 .Va DESTDIR ,
 .Va TARGET_ARCH
 and
 .Va TARGET
 should be set as with
 .Dq Li "make installworld" .
 .El
 .Sh ENVIRONMENT
 Variables that influence all builds include:
 .Bl -tag -width ".Va MAKEOBJDIRPREFIX"
 .It Va DEBUG_FLAGS
 Defines a set of debugging flags that will be used to build all userland
 binaries under
 .Pa /usr/src .
 When
 .Va DEBUG_FLAGS
 is defined, the
 .Cm install
 and
 .Cm installworld
 targets install binaries from the current
 .Va MAKEOBJDIRPREFIX
 without stripping,
 so that debugging information is retained in the installed binaries.
 .It Va DESTDIR
 The directory hierarchy prefix where built objects will be installed.
 If not set,
 .Va DESTDIR
 defaults to the empty string.
 .It Va MAKEOBJDIRPREFIX
 Defines the prefix for directory names in the tree of built objects.
 Defaults to
 .Pa /usr/obj
 if not defined.
 This variable should only be set in the environment or
 .Pa /etc/src-env.conf
 and not via
 .Pa /etc/make.conf
 or
 .Pa /etc/src.conf
 or the command line.
 .It Va NO_WERROR
 If defined, compiler warnings will not cause the build to halt,
 even if the makefile says otherwise.
 .It Va WITH_CTF
 If defined, the build process will run the DTrace CTF conversion
 tools on built objects.
 .El
 .Pp
 Additionally, builds in
 .Pa /usr/src
 are influenced by the following
 .Xr make 1
 variables:
 .Bl -tag -width ".Va SUBDIR_OVERRIDE"
 .It Va KERNCONF
 Overrides which kernel to build and install for the various kernel
 make targets.
 It defaults to
 .Cm GENERIC .
 .It Va KERNFAST
 If set, the build target
 .Cm buildkernel
 defaults to setting
 .Va NO_KERNELCLEAN ,
 .Va NO_KERNELCONFIG ,
 and
 .Va NO_KERNELOBJ .
 When set to a value other than
 .Cm 1
 then
 .Va KERNCONF
 is set to the value of
 .Va KERNFAST .
 .It Va LOCAL_DIRS
 If set, this variable supplies a list of additional directories relative to
 the root of the source tree to build as part of the
 .Cm everything
 target.
 .It Va LOCAL_ITOOLS
 If set, this variable supplies a list of additional tools that are used by the
 .Cm installworld
 and
 .Cm distributeworld
 targets.
 .It Va LOCAL_LIB_DIRS
 If set, this variable supplies a list of additional directories relative to
 the root of the source tree to build as part of the
 .Cm libraries
 target.
 .It Va LOCAL_MTREE
 If set, this variable supplies a list of additional mtrees relative to the
 root of the source tree to use as part of the
 .Cm hierarchy
 target.
 .It Va LOCAL_TOOL_DIRS
 If set, this variable supplies a list of additional directories relative to
 the root of the source tree to build as part of the
 .Cm build-tools
 target.
 .It Va LOCAL_XTOOL_DIRS
 If set, this variable supplies a list of additional directories relative to
 the root of the source tree to build as part of the
 .Cm cross-tools
 target.
 .It Va PORTS_MODULES
 A list of ports with kernel modules that should be built and installed
 as part of the
 .Cm buildkernel
 and
 .Cm installkernel
 process.
 .Bd -literal -offset indent
 make PORTS_MODULES=emulators/kqemu-kmod kernel
 .Ed
 .It Va STRIPBIN
 Command to use at install time when stripping binaries.
 Be sure to add any additional tools required to run
 .Va STRIPBIN
 to the
 .Va LOCAL_ITOOLS
 .Xr make 1
 variable before running the
 .Cm distributeworld
 or
 .Cm installworld
 targets.
 See
 .Xr install 1
 for more details.
 .It Va SUBDIR_OVERRIDE
 Override the default list of sub-directories and only build the
 sub-directory named in this variable.
 If combined with
 .Cm buildworld
 then all libraries and includes, and some of the build tools will still build
 as well.
 Specifying
 .Cm -DNO_LIBS ,
 and
 .Cm -DWORLDFAST
 will only build the specified directory as was done historically.
 When combined with
 .Cm buildworld
 it is necesarry to override
 .Va LOCAL_LIB_DIRS
 with any custom directories containing libraries.
 This allows building a subset of the system in the same way as
 .Cm buildworld
 does using its sysroot handling.
 This variable can also be useful when debugging failed builds.
 .Bd -literal -offset indent
 make some-target SUBDIR_OVERRIDE=foo/bar
 .Ed
 .It Va TARGET
 The target hardware platform.
 This is analogous to the
 .Dq Nm uname Fl m
 output.
 This is necessary to cross-build some target architectures.
 For example, cross-building for ARM64 machines requires
 .Va TARGET_ARCH Ns = Ns Li aarch64
 and
 .Va TARGET Ns = Ns Li arm64 .
 If not set,
 .Va TARGET
 defaults to the current hardware platform, unless
 .Va TARGET_ARCH
 is also set, in which case it defaults to the appropriate
 value for that architecture.
 .It Va TARGET_ARCH
 The target machine processor architecture.
 This is analogous to the
 .Dq Nm uname Fl p
 output.
 Set this to cross-build for a different architecture.
 If not set,
 .Va TARGET_ARCH
 defaults to the current machine architecture, unless
 .Va TARGET
 is also set, in which case it defaults to the appropriate
 value for that platform.
 Typically, one only needs to set
 .Va TARGET .
 .El
 .Pp
 Builds under directory
 .Pa /usr/src
 are also influenced by defining one or more of the following symbols,
 using the
 .Fl D
 option of
 .Xr make 1 :
 .Bl -tag -width ".Va -DNO_KERNELCONFIG"
 .It Va NO_CLEANDIR
 If set, the build targets that clean parts of the object tree use the
 equivalent of
 .Dq make clean
 instead of
 .Dq make cleandir .
 .It Va NO_CLEAN
 If set, no object tree files are cleaned at all.
 This is the default when
 .Va WITH_META_MODE
 is used with
 .Xr filemon 4
 loaded.
 See
 .Xr src.conf 5
 for more details.
 Setting
 .Va NO_CLEAN
 implies
 .Va NO_KERNELCLEAN ,
 so when
 .Va NO_CLEAN
 is set no kernel objects are cleaned either.
 .It Va NO_CTF
 If set, the build process does not run the DTrace CTF conversion tools
 on built objects.
 .It Va NO_SHARE
 If set, the build does not descend into the
 .Pa /usr/src/share
 subdirectory (i.e., manual pages, locale data files, timezone data files and
 other
 .Pa /usr/src/share
 files will not be rebuild from their sources).
 .It Va NO_KERNELCLEAN
 If set, the build process does not run
 .Dq make clean
 as part of the
 .Cm buildkernel
 target.
 .It Va NO_KERNELCONFIG
 If set, the build process does not run
 .Xr config 8
 as part of the
 .Cm buildkernel
 target.
 .It Va NO_KERNELOBJ
 If set, the build process does not run
 .Dq make obj
 as part of the
 .Cm buildkernel
 target.
 .It Va NO_DOCUPDATE
 If set, the update process does not update the source of the
 .Fx
 documentation as part of the
 .Dq make update
 target.
 .It Va NO_LIBS
 If set, the libraries phase will be skipped.
 .It Va NO_OBJ
 If set, no object directories will be created.
 This should only be used if object directories were created in a
 previous build and no new directories are connected.
 .It Va NO_PORTSUPDATE
 If set, the update process does not update the Ports tree as part of the
 .Dq make update
 target.
 .It Va NO_WWWUPDATE
 If set, the update process does not update the www tree as part of the
 .Dq make update
 target.
 .It Va WORLDFAST
 If set, the build target
 .Cm buildworld
 defaults to setting
 .Va NO_CLEAN ,
 .Va NO_OBJ ,
 and will skip most bootstrap phases.
 It will only bootstrap libraries and build all of userland.
 This option should be used only when it is known that none of the bootstrap
 needs changed and that no new directories have been connected to the build.
 .El
 .Pp
 Builds under directory
 .Pa /usr/doc
 are influenced by the following
 .Xr make 1
 variables:
 .Bl -tag -width ".Va DOC_LANG"
 .It Va DOC_LANG
 If set, restricts the documentation build to the language subdirectories
 specified as its content.
 The default action is to build documentation for all languages.
 .El
 .Pp
 Builds using the
 .Cm universe
 target are influenced by the following
 .Xr make 1
 variables:
 .Bl -tag -width ".Va MAKE_JUST_KERNELS"
 .It Va JFLAG
 Pass the value of this variable to each
 .Xr make 1
 invocation used to build worlds and kernels.
 This can be used to enable multiple jobs within a single architecture's build
 while still building each architecture serially.
 .It Va MAKE_JUST_KERNELS
 Only build kernels for each supported architecture.
 .It Va MAKE_JUST_WORLDS
 Only build worlds for each supported architecture.
 .It Va UNIVERSE_TARGET
 Execute the specified
 .Xr make 1
 target for each supported architecture instead of the default action of
 building a world and one or more kernels.
