* targets.c (bfd_target): Make ar_max_namelen an unsigned char.

	Add match_priority.
	* configure.in: Bump bfd version.
	* elfcode.h (elf_object_p): Delete hacks preventing match of
	EM_NONE and ELFOSABI_NONE targets when a better match exists.
	* elfxx-target.h (elf_match_priority): Define and use.
	* format.c (bfd_check_format_matches): Use target match_priority
	to choose best of multiple matching targets.  In cases with multiple
	matches rerun _bfd_check_format if we don't choose the last match.
