	Add -mdynamic-no-pic to compile flags for gcc.  On Mac OS X and Darwin,
	the compiler generates position-independent-code by default.  This allows
	an object file to be used for a dylib or executable without any thought
	on the developer's part, but generates less-efficient code.  Setting this
	flag on gcc speeds compiles by 3-5%.
	* config/rs6000/x-darwin: Add -mdynamic-no-pic to gcc build flags.
