Fix to %g/%u/%O spec parsing

[Nick Clifton]

I would like to submit the enclosed patch for approval.  It prevents a
spec string of "...%g ..." (ie one without a following suffix), from
passing the entire rest of the spec string as the suffix.

	* gcc.c (do_spec_1): Cope with %g/%u/%U options which do not have
	a suffix.
