    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
