From 15964864c051b31df7d2f9101fe8cc47854a0ab8 Mon Sep 17 00:00:00 2001 From: Oleg Verych Date: Sun, 10 Dec 2006 02:18:40 -0800 Subject: [PATCH] [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.
