* bfd-in2.h: Regenerate. 

* elf32-s390.c (elf_s390_adjust_gotplt): New prototype.
	(elf_howto_table): Rename R_390_GOTOFF to R_390_GOTOFF32. Add
	R_390_GOTOFF16, R_390_GOTOFF64, R_390_GOTPLT12, R_390_GOTPLT16,

	R_390_PLTOFF32 and R_390_PLTOFF64.
	(elf_s390_reloc_type_lookup): Likewise.
	(struct elf_s390_link_hash_entry): Add gotplt_refcount to keep track
	of GOTPLT references to a function.
	(link_hash_newfunc): Initialize gotplt_refcount.
	(elf_s390_check_relocs): Move allocation of local_got_refcounts array
	and creation of the got section out of the main switch. Add support
	for the gotoff, gotplt and pltoff relocations.
	(elf_s390_gc_sweep_hook): Add reference counting for gotoff, gotplt
	and pltoff.
	(elf_s390_adjust_gotplt): New function.
	(elf_s390_adjust_dynamic_symbol): Adjust gotplt refcount for removed
	plt entries.
	(allocate_dynrelocs): Add comment.
	(elf_s390_relocate_section): Change r_type to unsigned. Add support
	for gotoff, gotplt and pltoff relocations.
	* elf64-s390.c: Same changes as for elf32-s390.c.
	* libbfd.h: Regenerate.
	* reloc.c: Add BFD_RELOC_390_GOTOFF64, BFD_RELOC_390_GOTPLT12,
	BFD_RELOC_390_GOTPLT16, BFD_RELOC_390_GOTPLT32, BFD_RELOC_390_GOTPLT64,
