    kbuild: enable 'make AFLAGS=...' to add additional options to AS
    
    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
