Fix building core C compiler.
PowerPC unveiled that you can't reliably build a target libgcc until you have C library headers.
In fact you can't build it at all. The fact that it did build for some architectures was purely coincidental, and a mistake.
This fix should still allow to build uClibc-based toolchains (some ARM uClibc toolchains were build-tested).
