	with "s390:64-bit".
	* elf32-s390.c (elf_howto_table): Add 32 bit pc relative relocations.
	(elf_s390_reloc_type_lookup): Likewise.
	(elf_s390_check_relocs): Likewise.
	(elf_s390_gc_sweep_hook): Likewise.
	(elf_s390_relocate_section): Likewise.
	(elf_s390_object_p): Use renamed architecture define.
