This allows a clang bootstrap to happen, even when WITHOUT_CLANG is defined. This is a minimal version of a more extensive change which can be MFC'd more easily. However, we have to also test to see if we're building clang as not cc, since the bootstrap for that needs these cross tools and it is easier to build them in just one place. MFC after: 1 week END
