------------------------------------------------------
Subject: kbuild: fix-rR-is-now-default
From: Oleg Verych <olecom@xxxxxxxxxxxxxx>
`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.
