Subject: hack: arch: powerpc: drop register save/restore library from modules
Upstream GCC uses a libgcc function for saving/restoring registers. This
makes the code bigger, and upstream kernels need to carry that function
for every single kernel module. Our GCC is patched to avoid those
references, so we can drop the extra bloat for modules.
