Problem with c++types on s390*.

[Roland McGrath]

Really the reference data sets need to be selected by patterns matching the
tuples, so the data can be filed under i?86-blah and suchlike.  That
doesn't work so well for file names, though.  It would be simple to hack
the scripts so that there is just one c++-types.data with a section for
each tuple pattern and its data.  The only downside is the one big file in
cvs instead of separate files.  But if noone objects, I can do that hack.
