I had a thinko in processing the switches for quad memory, in that it cleared
quad memory on 32-bit, and then OR'ed in the switches from the -mcpu, when it
should have cleared it after the OR.

I have committed this patch as obvious (after checking it out to make sure it
fixes the problem and builds):

	* config/rs6000/rs6000.c (rs6000_option_override_internal): Move
	test for clearing quad memory on 32-bit later.
