ld: Clear map_head_is_link_order for .gnu_object_only

Browse Source 
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.
