Please do!

That is very useful for testing and developing new modules.
I learnt a lot from you in this regard and used that kind
of syntax to the extreme in some other non-kernel project
of mine. There it included also ccflags, asflags and so on.

I further split that into -debug-y and -optimize-y flags,
but that was just for my own convenience.
