yes, I did, and the problem is that this is extreamly slow if you've
only modified one line of one file for testing...  Do you build all of
your kernels this way??

I really hate having to remeber and type those everytime that I build a
kernel...  You're also forgetting NO_KERNELCONFIG=yes to that... since
if it's just a typo, you usually don't need a config for a typo...

yes, there are other complex solutions, but I'd like a simplier solution,
and one that is a lot more friendly to my fingers...
