Does this mean _all_ shared libs, including those that live in
/usr/pkg/lib?  Do the ones from /usr/pkg/lib go into their own 
directory /emul/aout/usr/pkg/lib or into the standard place?

Does the kernel have to be built with OBJECT_FMT = ELF, or will
the old build procedures work?

(suggest continuing on with original numbering, rather than
going back to 4!  :)

I think I'd recommend doing a ``make cleandir'' here before the
first ``make''

Ditto with the ``make cleandir''
