* elf.c (_bfd_elf_make_section_from_shdr): Don't set SEC_EXCLUDE
	for SHT_GROUP sections.

	* ldlang.c (lang_add_section): Set SEC_EXCLUDE for SEC_GROUP
	sections when doing a final link.  Clear SEC_EXCLUDE when doing
	a relocable link, except for SEC_DEBUGGING sections.
	* emultempl/elf32.em (gld${EMULATION_NAME}_place_orphan): Use the
	same condition here to drop SEC_EXCLUDE orphan sections.
