Just 'make all-gcc'. It's only things in the 'all-target-*' makefile
targets that need target C library headers.
In the beforetime, the long long ago, the build of libgcc was intertwined
directly with the compiler build. But for several versions now (all that
we support for building libc, I'm pretty sure), it's just a normal target
library like all the others (libstdc++ et al) in the build system.
