PATCH: New config, Darwin / Mac OS X (host-only)

[Stan Shebs <shebs at apple dot com>]

Here are the bits I mentioned yesterday.  They should be
noncontroversial, the worst being the designated initializer
hack which is needed for unbelievably lame reasons that I hope
will go away once we get onto current GCC...

	* config/rs6000/xm-darwin.h: New file, Darwin host definitions.
	* config/rs6000/x-darwin: New file, Darwin host fragment.
	* configure.in (powerpc-*-darwin*): New host.
	* configure: Regenerate.
	* system.h (HAVE_DESIGNATED_INITIALIZERS):  Allow this to be
	overridden by a config file.
