[PATCH] S/390: Run md tests with -march=native instead of -march=z13.

[Dominik Vogt]

The attached patch fixes an md test execution problem on S/390.
The tests would be built with -march=z13 but executed even on
older machines.  Build with -march=native instead, so executing
the tests should work on any machine generation.

Tested on s390x biarch, but not bootstrapped or regression tested.

Ciao

Subject: [PATCH] S/390: Run md tests with -march=native instead of
 -march=z13.

Otherwise the tests are built and _run_ with -march=z13 on machines prior to
z13, possibly causing failures due to illegal instructions.
