I don't know what the issue is with buildkernel specifically, I never
looked into it. Buildworld had other issues like rescue/rescue not being
AUTO_OBJ safe. That's fixed. I forget the details of buildworld as well.
One of the simpler changes is to remove the 'make obj' treewalk and
prefer .OBJDIR/OBJTOP over other ${CANONICALOBJDIR} ${OBJTREE} type
hacks. My patches are quite mangled with the idea of moving to
/usr/obj/CURDIR/TARGET.TARGET_ARCH/RELDIR and I need to split it all up
still.

It does not fix the issues.

Wrong^
Note we have 'cd /usr/obj/....' and 'MAKEOBJDIRPREFIX=3D/usr/obj' in
there, so we get a nested /usr/obj/.CURDIR problem of /usr/obj/usr/obj.

Wrong^
I will look into this as part of my larger patch, but it's likely due to
the first bug.
