I don't think there's a consistent cross-platform flag.

Scanning the source, ia64-hpux recognises -milp32 and -mlp64 but it
doesn't look like these are implemented for Linux - even in CVS GCC.

Either these simply haven't been implemented or someone has made the
decision that ia64-linux will not support ILP32. If you'd like to
volunteer to implement this, or would like to discuss this further,
you'd probably do better on the main gcc mailing list.
