hmm, afaict this isn't what a stock gcc build will do. You can easily enable 
it though by copying the .S.so .s.so rule from libgcc3/libgcc/Makefile to 
libgcc3/libgcc_s/Makefile and rebuilding.

The NOTYPE is because

	gnu/dist/gcc/gcc/config/sh/lib1funcs.asm

doesn't do

        .type   foo, @function

I'm not sure that helps...
