Darwin: Allow for as versions that need '-' for std in.

Recent versions of Xcode as require a dash to read from standard
input.  We can use this on all supported OS versions so make it
unconditional.  Patch from Mark Mentovai.

gcc/ChangeLog:

	* config/darwin.h (AS_NEEDS_DASH_FOR_PIPED_INPUT): New.
