	* elfxx-target.h (elf_backend_can_refcount): Define.
	(elfNN_bed): Init can_refcount.
	* linker.c (_bfd_link_hash_newfunc): Get rid of a few casts.
	(_bfd_generic_link_hash_newfunc): Likewise.
	* elf32-cris.c (cris_elf_check_relocs): Modify for refcounts
	starting from zero.
	(elf_backend_can_refcount): Define.
	* elf32-hppa.c (elf32_hppa_check_relocs): Modify for refcounts
	starting from zero.
	(elf32_hppa_copy_indirect_symbol): Make static to agree with
	prototype.
	(elf_backend_can_refcount): Define.
	* elf32-i386.c (elf_i386_check_relocs): Modify for refcounts
	starting from zero.
	(allocate_dynrelocs): Set plt/got.offset rather than *.refcount.
	(elf_i386_finish_dynamic_symbol): Expand SHN_UNDEF comment.
	(elf_i386_finish_dynamic_sections): Use local var so line < 80 chars.
	(elf_backend_can_refcount): Define.
	(elf_i386_copy_indirect_symbol): Make static to agree with
	prototype.  Formatting fix.
