It's handy in the sense that it'd be nice to install all arch manpages
on some machines, e.g., I develop arm stuff on amd64 and there are
some drivers that simply aren't applicable to amd64, I'd like to be
able to find those. I think the implementation is a bit odd, though,
leading into:

I guess I haven't read the context much here, but I don't see why
either. /usr/bin/man's built-in search behavior checks
$mandir/$machine and $mandir/$machine_arch before $mandir, it seems
like we should be leaving them there and letting man do its thing. If
you need a non-native arch then you can hopefully just poke around the
arch subdirs (presumably mostly section 4 pages) to figure it out.
There's a reason they're arch subdirs, and trying to install links or
arch-specific pages into the main $mandir is asking for trouble when
we actually have conflicting pages for whatever reason between archs.
