Existing biarch magic already takes care of this issue if we maintain it
with shlib-versions lines.

Hmm. I hadn't thought about it before, but this is a pretty good reason
not to have LIBGCC_S_SO defined in the installed <gnu/lib-names.h> IMHO.
Let's just add a trivial sysdeps/.../libgcc_s.h that defines LIBGCC_S_SO by
hand, and maintain that by hand.
Thanks,
