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).

1 Original patch from H.J. Lu, as reported there:
2 http://www.nabble.com/PATCH:-Use-short-for-fnstsw-td14775171.html
4 fnstsw stores 16bit into %ax. The upper 16bit of %eax is unchanged.
5 The new assembler (binutils-2.18.50.0.4 and up) will disallow "fnstsw %eax".
