Change Details

Allow the build process to find host binaries during the host-symlinks target when cross-building on non-FreeBSD systems.

Allow the build process to find host binaries during the host-symlinks target when cross-building on non-FreeBSD systems. Whilst most non-FreeBSD systems have all the needed tools in /sbin:/bin:/usr/sbin:/usr/bin:/usr/local/bin (the final path added by host-symlinks itself), Homebrew for macOS on Arm defaults to /opt/homebrew/bin, other more niche systems may also deviate and users may expect tools in a customised PATH to be picked up, unlike on FreeBSD where we want to ensure everything comes from base. In particular, (un)xz are needed from Homebrew on macOS, and thus cannot be found on Arm without this. Note that non-FreeBSD builds enforce BUILD_WITH_STRICT_TMPPATH, and so the actual main build steps will still use a sanitised PATH.
