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.
