* elf-bfd.h (struct elf_backend_data): New member got_elt_size.

	(_bfd_elf_default_got_elt_size): Declare.
	* elflink.c (struct alloc_got_off_arg): Replace member got_elt_size
	by new member info.
	(elf_gc_allocate_got_offsets): Adjust for calling bed->got_elt_size
	to get the element size instead of using a gofarg entry.
	(bfd_elf_gc_common_finalize_got_offsets): Similar.
	(_bfd_elf_default_got_elt_size): New function.
	* elfxx-target.h: New macro elf_backend_got_elt_size.
	(elfNN_bed): Use it.
