Darwin: Guard two macros in darwin.h.

Browse source 
Work on the Arm64 port shows that these two macros can be declared
ahead of the version in darwin.h which needs to override (for X86
and PPC this wasn't needed).

gcc/ChangeLog:

	* config/darwin.h (ASM_DECLARE_FUNCTION_NAME): UNDEF before
	use.
	(DEF_MIN_OSX_VERSION): Only define if there's no existing
	def.
