	* elf.c (bfd_elf_set_group_contents): Assign sh_info for ld -r when
	the signature symbol is global.
	* elflink.c (elf_link_input_bfd): Ensure group signature symbol
	is output when ld -r.  Set group sh_info when local.
	* linker.c (default_indirect_link_order): Handle group sections
	specially.
ld/
	* ldemul.c (ldemul_place_orphan): Add "name" param.
	* ldemul.h (ldemul_place_orphan): Update prototype.
	(struct ld_emulation_xfer_struct <place_orphan>): Likewise.
	* ldlang.c (lang_place_orphans): Generate unique section names here..
	* emultempl/elf32.em (place_orphan): ..rather than here.  Don't
	directly use an existing output section statement that has no
	bfd section.
	* emultempl/pe.em (place_orphan): Likewise.
	* emultempl/pep.em (place_orphan): Likewise.
	* emultempl/beos.em (place_orphan): Adjust.
	* emultempl/spuelf.em (spu_place_special_section): Adjust
	place_orphan call.
	* emultempl/genelf.em (gld${EMULATION_NAME}_after_open): New function.
	(LDEMUL_AFTER_OPEN): Define.
