Yes that is obvious.  When one sets NO_TOOLCHAIN they are obviously
building world on a workstation and doing the 'make installworld' with a
destination on the "embedded" machine.

If NO_TOOLCHAIN is set, it is OK to assume a [mostly] complete world on
the build machine and that it matches the sources being built.
NO_TOOLCHAIN however, would keep from installing compiler,
/usr/include/*, and /usr/lib/*.a.  Also any optimization of 'make
buildworld' time should occur knowing that things like lib*.a won't be
used or installed.
