Subject: [PATCH 8/8] kbuild: remove useless warning

From: Artem Bityutskiy <artem.bityutskiy@...ux.intel.com>

This patch removes annoying warning:

Makefile:708: "WARNING: Appending $KCFLAGS (-Wno-sign-compare) from command line to kernel $CFLAGS"

which is printed every time I use KCFLAFS. The commit which introduced the
warning:

69ee0b3 kbuild: do not pick up CFLAGS from the environment

tells about the problems when people have CFLAGS in their environment,
then switches to KCFLAFS which should be enough to solve the issue, but
it anyway introduces a warning. I think it is too much and I find this
warning very annoying - why should we warn users when they use the
build system properly?
