WRONG. This is not how it works now! I don't know what this weird
fixation people have with trampling on /usr/src now is, but there's no
reason for this to work because it's not looking in ${.SRCDIR}/obj and
never will again. Don't be fooled by the `objlink' stuff as that's
only user convenience - the make system does *not* follow the link!

"make obj" is recommended.

Exactly! That's correct.

> $ export MAKEOBJDIR=obj
Again, this is wrong and I explained this! MAKEOBJDIR is an absolute
path now, NOT the name of the obj directory itself.
> $ mkdir obj
> $ make # still builds in ".", not OK
Totally OK. This is correct.
> $ mkdir obj/tmp obj/tmp/cat
> $ make # now builds in /tmp/cat/obj/tmp/cat :-(.
And still correct.
Sorry Bruce, but there's nothing broken here except your expectation
that everything should be still broken in the ways it was broken
before! :-)
