The variable AFLAGS is a wellknown variable and the usage by kbuild may result in unexpected behaviour. On top of that several people over time has asked for a way to pass in additional flags to gcc. This patch replace use of AFLAGS with KBUILD_AFLAGS all over the tree. 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>
