Force -m31/-m64 based on s390/s390x target.
Force -march=z990. The TCG backend will always require the
long-displacement facility, so the compiler may as well make
use of that as well.

Some hosts (amd64, ia64) have an ABI that ignores the high bits
of the 64-bit register when passing 32-bit arguments. Others,
like s390x, require the value to be properly sign-extended for
the type. I.e. "int32_t" must be sign-extended and "uint32_t"
must be zero-extended to 64-bits.

So I took Uli's patch, cleaned it up and present it to you again :-).

The TCG translator will *not* work in 32-bit mode, and there is a
check added to query_facilities to enforce that.
However, QEMU can run in KVM mode when built in 32-bit mode, and
this patch is just good enough to enable that method to continue.
