I think DEBUG_DRIVER should exist in local config so that a developer 
can easily toggle it without modifying the common_base, which should 
serves as repository rather than toggle.

I do see the problem that having an option in common_base and then 
having it again in local config without overriding (=n) - is non-intuitive.

But, I still feel it is easier to control changes in local config - 
(make T=<local config>) is easily visible.
