[PATCH] kbuild: fix-rR-is-now-default

`make -d help | grep Makefile` shows patterns, where make tries to rebuild
included and top makefiles.

While `make -rR is now default' commit should fix this, actually, it was just
a little janitorial.

This fix is aimed to complete cancelling implicit rules.
