Patch works just fine, thanks. I also ran some automatic testing
and it seems that all .c files are properly tracked by build system -
whenever I touch one and run make, it gets rebuilt.

None of include files are tracked, though.
"find -name '*.h' | xargs touch" + "make" only runs oldconfig
but does not rebuild any object files.
