AUTO_OBJ: Disable in non-build targets.
There's no reason to create object directories for targets like 'installworld' or 'distributeworld', and the others in this list. Specifying MK_AUTO_OBJ as a make argument allows circumventing this if needed for some reason. This fixes mergemaster creating a full object tree due to doing a 'make installconfig' tree walk.
