If we agree on this as the base infrastructure I would
like you to introduce it as part of adding Coccinelle support.

That should not touch the existing targets - but only
add Coccinelle support. But in a way so we have the
infrastructure in place so we can later move the other targets later.

I like the latter.
If you do "make coccicheck" then you can show a list of
possible mode's. And if MODE is set you use this mode.
