Having different naming schemes for identical bits is risks confusion
and inconsistency for both ports mainainers and ports users.  I agree
that your scheme is attractive, but I think that consistency is more
important.  Also, I'd say that we should probably think about leaning in
the direction of the LSB for linux compat.  So my vote is that on all
platforms, /compat/linux is for 32-bit and /compat/linux64 is for
