See Michael's concerns about security.  By doing that, we would affect
much more people than simply those who want to actually use
COMPAT_NETBSD32.

That's easily doable.

I've finally had a look at the diff between majors.amd64 and
majors.i386.

It's not a pleasant sight.  At this point I think it's either we do the
magic symlinks dance on i386 or we kindly explain our amd64 users that
