Well, sort of.  We try to support all available ABIs, so recognizing
s390 and s390x is similar machines might not be bad, as long as we try
the 64-bit ABI for the latter, but allow ABI=32 if the environment
supports it.

  Fixed with the attached patch.
Thanks.  The only change strictly needed is the one for configure.in.

I still think we should support s390x somewhat better than this, to
allow some sort of performance.  But perhaps there are no useful
64-bit multiply instructions?
