Re: ARC port broken reloc processing 

* elf32-arc.c (ARC_ELF_HOWTO): Delete.
	(arc_elf_howto): New function.
	(bfd_elf32_bfd_reloc_type_lookup): Use it in place of existing
	init code.
	(bfd_elf32_bfd_reloc_name_lookup): Use arc_elf_howto.
	(arc_info_to_howto_rel, elf_arc_relocate_section): Likwise.
	(elf_arc_check_relocs): Likewise.
