This patch handles ELF_RTYPE_CLASS_EXTERN_PROTECTED_DATA for MIPS in a
way similar to other architectures.

I've *not* committed this patch since, while it seems the logical
change for this purpose, it doesn't actually fix the
elf/tst-protected1[ab] failures; probably a binutils fix is needed as
well.  Perhaps someone familiar with MIPS binutils would like to look
at that?

	[BZ #17711]
	* sysdeps/mips/dl-machine.h (elf_machine_type_class): Handle
	ELF_RTYPE_CLASS_EXTERN_PROTECTED_DATA.
	* sysdeps/mips/dl-sysdep.h: New file.
