cmd/ld, cmd/5l, cmd/go: a workaround to support linking thumb library
     we pass -mlong-calls to gcc so that we don't need to worry about
generating mode changing veneers. But, we still need to address this
problem later.
     In preparation of CL 5822049.
(Ubuntu uses a thumb libgcc, so without this CL, the new libgcc test
in CL 5822049 will break the build)
