Just so I'm sure I understand, it just works by checking for $WRKDIR first
and only cleaning if it exists right?  Therefore eliminating up to 3000
calls to make :)  So my only question is if it does the right thing if you
have something like

WRKOBJDIR=             /u2/disk1/build/pkgsrc

in /etc/mk.conf and possibly a read-only /usr/pkgsrc

In the first case, /usr/pkgsrc/foo/bar/work will be a link to
/u2/disk1/build/pkgsrc/foo/bar/work  and in the second,
/usr/pkgsrc/foo/bar/work will never even exist, but
/u2/disk1/build/pkgsrc/foo/bar/work will.  As long as those 2 variations
are dealt with then I think this is a good idea.
