Invalid use of -m32 on certain targets

Short note, internally at SAP we have a proprietary port for HPUX
parisc and yes, upward growing stack is quite a problem. We had to
make (and continue to maintain) a lot of downstream changes which deal
with that. So I doubt that even if you manage to build the VM would be
running for long.

Best regards, Thomas
