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. Patch was tested on following architectures: alpha, arm, i386, x86_64, mips, sparc, sparc64, ia64, m68k, s390 Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
