: : powerpc, add WITHOUT_CLANG=yes to /etc/src.conf, as described in

: MACHINE_ARCH is still amd64 until we start to build the sparc64

: based on architecture is going to fail.

And even if you add WITHOUT_CLANG to your src.conf, we still always
build some of the clang infrastructure in the bootstrap tools
phase...  But we have to do that to avoid getting not being able to
build clang on an architecture that doesn't have it for an
architecture that does.
