[pypy-dev] s390x the last failing tests

[David Edelsohn]

Debian apparently supports all z/Arch processors, so the toolchain
defaults to much older processor model.  For zEC12 and above, one must
explicitly invoke GCC with -march=zEC12.  I set CFLAGS and the
translation is much happier.

The s390x buildbot should explicitly use -march=zEC12.

Thanks, David
