Yeah, that's certainly more convenient than "make --debug".

That said, I was more thinking of not any particular "oh, it's
recompiling everything" situation (by then it's too late, obviously),
but if somebody has been looking at tools for finding and maybe
breaking some of our deeper include chains.

I know it has come up before (the x86 people did the
<linux/schedule.h> split some years ago) and then it was all manual.
But I was kind of hoping that maybe some of the kbuild people had
looked at this?
