* config/tc-arm.c (do_t_ldmstm): Change BFD_RELOC_NONE to

	BFD_RELOC_UNUSED.
	(do_t_push_pop): Likewise.
	(md_assemble): Likewise.
	(md_apply_fix3): Handle BFD_RELOC_NONE correctly, make BFD_RELOC_UNUSED
	same as previous meaning of BFD_RELOC_NONE.
	(create_unwind_entry): Output dependency on the required personality
	routines.
	testsuite/gas/arm/unwind.d: Alter expected output to include dependency
	on __aeabi_unwind_cpp_pr[01].
