Good point - I compared the result of 'make installworld' between stock Fre=
eBSD
and with MK_TOOLCHAIN=3Dno removed, but I did not notice if it caused libll=
vm,
libclang to be built. Clang itself wouldn't be built, because the compat32
stage does nothing with bin/usr.bin etc.

The sanitizer runtimes are a bit of an interesting case. It seems they do
belong with MK_TOOLCHAIN, they really are a runtime component tied to the C=
lang
version in use.

Maybe we should not try to be too generic / "clean" here and just pass in a
COMPAT32 flag to the submakes, and have the individual Makefiles do the rig=
ht
thing (skipping headers and all not-runtime-support libs)?
