I'd argue that eliminating the _32/_64 suffixes through unification and
not adding any more would be better.  Renaming at this point seems like
the wrong side of the cost/benefit line.  When the makefiles finally get
unified, that would be a natural list of what is 32 bit-only and what
is 64 bit-only, and additional suffixes wouldn't add much to that.

Just another voice,
