I wouldn't, because if an address is passed to the kernel, it comes across
as 32 bits.  But what _do_ we do on modern, 32-bit MIPS?  Are we still O32?
It does kind of look like it -- all our 32-bit MIPS ports' sets files seem
to be linked to ../../../shared/mipsel/ which must be O32 since it is also
used for the pmax sets.
