Summary

Make usr.bin/netstat/Makefile use the header files from the build tree like usr.bin/truss/Makefile does. Otherwise netstat won't compile on older system. Clean up formatting according to style.Makefile(5).

Test Plan

Run make in usr.bin/netstat using source from CURRENT on FreeBSD 12.1.

Does it make sense to group the include lines, even if not on one line

usr.bin/netstat/Makefile

This looks bogus to me. We're already CD'd to ${.OBJDIR} so we'll pickup files there automatically. why is it needed?

More specifically, what's broken when you do a 'make buildenv' and then 'make' to build this? There's a number of issues building on older systems, and adding this only catches a small subset of them...

This was already in the Makefile. I don't know what it's needed for and I don't know where the CD happens you mentioned but quite a few other Makefiles seem to contain such a CFLAGS line.

When you just do a 'make buildenv' and then 'make' things seem to become more broken. make can't even find cdefs.h. anymore. One might need to do 'make toolchain' before but that takes ages to finish. Including the above CFLAGS line makes netstat buildable from its directory without any further requirements.

On the other hand, I don't know much about your build process. Maybe my suggested fix is not the right one if one takes a wider context into account.

'make toolchain' of a CURRENT source tree doesn't finish on 12.1. It seems to be unhappy about the FreeBSD version:
