Or set "MKOBJDIRS= yes" in /etc/mk.conf. This always does a "make obj"
right after "make cleandir".  Objdirs plus UPDATE=1 sets a trap,
though, if you use it inappropriately after major changes to the build
structure. You could end up with objects outside of the "obj" dir that
are never recompiled.
