It can't be done quite so simply. hpux supports both
LP64 and ILP32 modes, but no one else does. I suppose
we could make the -milp32 switch universal and just
ignore the lack of surrounding environmental support
for most platforms.

Yes. These don't have anything to do with the psabi,
but rather with how the backend is written.
