Even more than that. As it also builds headers and libraries, it's
also sufficient to build any particular part of the world, e.g., by
using these commands:
: # (slow) you do this once
: for target in i386 sparc64 amd64; do
: make toolchain TARGET_ARCH=${target}
: done
: # (fast) you repeat this for each subpart of the world
: for target in i386 sparc64 amd64; do
: for bit in bin/sh usr.bin/awk ...; do
: for stage in obj all; do
: make ${stage} TARGET_ARCH=${target} SUBDIR_OVERRIDE=${bit}
: done
: done
: done
The below patch can be committed if necessary, and used to build
a toolchain sufficient to build fresh kernels.
