full build log
I actually need Go on a MIPS32 machine so I'm building a toolchain with
Gentoo's crossdev (had to baby it some) and I ran into this error. I built it
with gcc-5.4.0 because I forgot to switch out my system compiler, but we're
past that at this point anyway.

The link succeeds if I pass -lgcc_s. So should libgcc/config/t-slibgcc-libgcc
use be writing -lgcc_s for this arch or is something else just looking for
libgcc.so.1 instead of libgcc_s.so.1 and then lying about it?
