That's not quite the problem - with the exception of the boundary cases
of compleatly broken CONFIG_BLAH combinations... You have the fine
.confg file there you know... Count them n and take the n! for all the
possible config choices. Then you will see that THERE CAN'T be any
automatic approach then just what I have described above (ie. going
directly into the compiler) and doing the CONFIG_ handling by hand.
(I mean scripting for the most appriopriate choices...)

Yeah... let me be nice to you as well Source Navigator got released
for free - since the project died inside RedHat anyway due to the
fact that it's full of the worst coding practices I ever saw - like
for example literally copy and paste Tcl/Tk/iTcl and such. So instead
of buring it they just threw it "out of the window" for "free".
