I also think that native N32 support would not be very interesting if it
bounds us to duplicate all libraries like IRIX does. But it remains
quite usefull to support N32 binaries for IRIX binary compatibility.

But I still don't have much clues about how to implement it... I assume
the first step would be to define somewhere a struct frame_n32?
