* elfxx-sparc.c: New file.

* elfxx-sparc.h: New file.
	* Makefile.in (BFD32_BACKENDS): Add elfxx-sparc.lo
	(BFD32_BACKENDS_CFILES): Add elfxx-sparc.c
	(elfxx-sparc.lo): New rule.
	(elf32-sparc.lo): Add elfxx-sparc.h dependency.
	(elf64-sparc.lo): Likewise.
	* configure.in (bfd_elf32_sparc_vec): Add elfxx-sparc.lo
	(bfd_elf64_sparc_vec): Likewise.
	* configure: Regenerate.
	* elf32-sparc.c: Remove common code now in elfxx-sparc.c
	* elf64-sparc.c: Likewise, also use elf64_sparc_*() naming
	which is more consistent with elf32-sparc.c
