yeah I guess a way is to always have BBPATH non empty by default and
then layers append their respective
BBPATHS to it and all falls into place.

In OE-Core it still wont work since there BBPATH is empty by default
and we can not assume some initial value for
it since user may place OE-Core anywhere in his layer heirarchy
