ITYM "multiply".

Binutils recently changed the maximum page size for o32 to 64k, and
has the same for n32/n64. I think we should be consistent.

Btw, 64k page sizes are also the maximum on IRIX, this suggests it
provides enough headroom to build large systems. (This is only my
guess, and not backed up by data.)
