The attached patch disables the test ifcvt-4.c on s390 and on
s390x with -31, and adds -march=z196 for s390x. It should no
longer fail on s390 and s390x.
Tested on s390x biarch.
Ciao

Subject: [PATCH] PR 68749: S/390: Disable ifcvt-4.c for -m31.
The test needs the conditional move pattern which is available only with
-march=z196 or higher and -m64.
