* config/darwin.c (machopic_symbol_defined_p): In addition to

	being SYMBOL_REF_LOCAL_P, a symbol must also be
	! SYMBOL_REF_EXTERNAL_P, as only those are _always_ locally
	defined in this output file, or translation unit in the case
	of IMA not being used.
	(machopic_output_indirection): SYMBOL_REF_LOCAL_P symbols
	never need .indirect_symbol when indirecting.
