    gold/
    	PR gold/21054
    	* mips.cc (Mips_got_info::record_global_got_symbol): Don't add symbol
    	to the dynamic symbol table if it is forced to local visibility.
    	(Target_mips::do_finalize_sections): Don't add __RLD_MAP symbol to the
    	dynamic symbol table if it is forced to local visibility.
