From 06c5040cdb13d27adad118f2fbfae905a1911b37 Mon Sep 17 00:00:00 2001 From: Sam Ravnborg Date: Mon, 15 Oct 2007 22:17:25 +0200 Subject: kbuild: enable 'make CPPFLAGS=...' to add additional options to CPP The variable CPPFLAGS is a wellknown variable and the usage by kbuild may result in unexpected behaviour. This patch replace use of CPPFLAGS with KBUILD_CPPFLAGS all over the tree and enabling one to use: make CPPFLAGS=... to specify additional CPP commandline options.
