Because n32 requires 64-bit registers.

Packages are going to be a real killer for us given the bugs in our
binutils that make it refuse to link "incompatible" cputypes together,
even though there's no problem with doing so.  We should probably just
remove that behavior and stop complaining about it and then half this
complexity goes away, except for the question of whether packages need
to match world wrt soft- and hard-float.
