Empty libgcc_s.

This library is built just so that something is present in
/usr/lib/libgcc_s.so.1.  This is needed for dynamically programs built
with gcc, which might reference that library at runtime (i.e. all pkgsrc
packages). The necessary symbols are in libc however, so when built on a
clang-only system, so an empty library is a working stopgap.
