3871         version of a relaxable macro is needed.  Return -RELAX_SECOND if the

3873         (tc_gen_reloc): Remove relaxation handling.
3874         (md_convert_frag): Go through the fixups for a relaxable macro and
3875         mark those that belong to the unneeded alternative as done.  If the
3876         second alternative is needed, adjust the fixup addresses to account
3877         for the deleted first alternative.
