In mk/bsd.obj.mk:

        here=`${PAWD}`; subdir=$${here#${BSDSRCDIR}/}; \
        if test $$here != $$subdir ; then \

If your source tree you're building in isn't /usr/src and you haven't 
redefined BSDSRCDIR to point to the place you're at, it'll fall through here
and make real dirs and not symlinks.

Here's the file I source when I build:

BSDOBJDIR=/home/jmc/src/trunk/obj
BSDSRCDIR=/home/jmc/src/trunk/src
DESTDIR=/home/jmc/src/trunk/build
KERNOBJDIR=/home/jmc/src/trunk/obj/sys/arch/i386/compile
MKOBJDIRS=yes
RELEASEDIR=/home/jmc/src/trunk/release
UPDATE=1
export BSDOBJDIR
export BSDSRCDIR
export DESTDIR
export KERNOBJDIR
export MKOBJDIRS
export RELEASEDIR
export UPDATE
mkdir -p $KERNOBJDIR

I get all the proper behavior for obj dirs this way (and *nothing* ever shows
up in my src tree that wasn't checked in). MKOBJDIRS is handy to force
rebuilds as new source dirs you might not catch at times.
