[kvm-unit-tests PATCH v1] s390x: explicitly mark stack as not executable

[Nico Boehr <nrb@linux.ibm.com>]

With somewhat recent GCC versions, we get this warning on s390x:

  /usr/bin/ld: warning: s390x/cpu.o: missing .note.GNU-stack section implies executable stack
  /usr/bin/ld: NOTE: This behaviour is deprecated and will be removed in a future version of the linker

We don't really care whether stack is executable or not since we set it
up ourselves and we're running DAT off mostly anyways.

Silence the warning by explicitly marking the stack as not executable.
