Might sound a stupid question, but why have a CONFIG_ option and
a global definition based on it rather than each arch defining it
as part of the base types ? I don't have a firm preference for one
or the other at this point, I can see pro and cons to both approach,
so I'm curious to see what others think about it.

Cheers,
Ben.
