The creating line is the clue, it is just obj
rather than say /usr/obj/usr/src/bin/cat

Do you have MAKEOBJDIRPREFIX set in env?
Or are you relying on bsd.obj.mk to set
CANONICALOBJDIR:=/usr/obj${.CURDIR}

?

Since we need to do auto.obj.mk *very* early (so .PATH is correct),
it is probably relying on MAKEOBJDIRPREFIX or MAKEOBJDIR
(I always have MAKEOBJDIR set) since bsd.obj.mk will not be included
yet.

If that's all the case though I wouldn't expect it to work any better on
subsequent runs.
