    ld: Clear map_head_is_link_order for .gnu_object_only
    
    Clear map_head_is_link_order when generating .gnu_object_only section so
    that lang_add_section can add new sections and .sframe sections will be
    properly merged by _bfd_elf_merge_section_sframe.
    
            PR ld/33146
            * ldlang.c (cmdline_emit_object_only_section): Clear
            map_head_is_link_order.
            * testsuite/ld-plugin/lto.exp (as_gsframe): New.
            (lto_link_tests): Add $as_gsframe to compile lto-4b.o and
            lto-4c.o.
