  We currently enable the vector extensions also for -march=z13 -m31
mesa which is very wrong.

Not a regression but an obvious fix, so I've committed it to mainline
now. Will have to cherry-pick it for stable branches as well.

gcc/ChangeLog:

	* config/s390/s390.cc (s390_option_override_internal): Check zarch
	flag before enabling -mvx.
