    arch/x86/Makefile.inc: Re-enable -Wa,--divide assembler flag
    
    In the follow-on patches, we use constant division to calculate the
    number of elements in an assembly structure. Since the size of one
    element is not a power of two for all structures, we can't bit shift.
    This allows us to do the computation at assembly time rather than
    runtime.
