Oh I missed this part^

By the way UPDATE_DEPENDFILE is not really a user variable and setting
it may break things.

Aha /usr/obj/usr/obj.

That was in Renato's report as well.

The bug is WITH_AUTO_OBJ. I just confirmed that. A bunch of errors occur
when doing the first build and the opt_*.h files are not generated in
the "proper" place by config(8).

WITH_AUTO_OBJ is not really workable yet in buildworld/buildkernel. I
have patches that I will commit soon to add support for them (meaning to
work as it all does not but without a 'make obj' tree walk).
