    configure: disable cpunop if the check fails
    
    Moving cpunop from the HAVE_LIST to the ARCH_EXT_LIST_X86 has the side
    effect of enabling it. The semantics of the check have to be changed
    from enable if successful to disable if unsuccessful. This was missing
    in 2b0bb69997c2416e74f41aa1400ce983bf8775c0 causing build errors with
    nasm.
