[This reply is targeted towards everybody taking part of this thread,
and does nto relate to this message in particular--I just picked one
at random.]

It does appear that indeed the buildkernel target is broken with
regards to building a kernel from the same sources as the running one
without a populated /usr/obj.  I remember trying this in the past, and
it worked.  I can now see your rationale for this thread and the
handbook patch, however, I agree with Neil that buildkernel should be
fixed, not the handbook.

The following patch sort of addresses the problem.  I can get
buildkernel to finish without errors.  If you have time, please try it
out.  It is proof-of-concept (that buildkernel can be fixed) quality
at best (in other words, don't run this on your mission-critical
machines), but it does seem to work (actually, I had to test it on a
slightly newer tree than what I have running, so YMMV).
