hey, even a blind squirrel finds the occaional acorn. details to
follow after i'm *sure* i didn't screw anything up.

sorry, that was badly worded so let me turn this into a much simpler
question. is there any drawback to building a toolchain using
sanitized headers as opposed to a full kernel source tree? i ask
since it appears that it's the kernel configuration step that's
causing the problem, and that's obviously bypassed if you're just
does that make sense?
