Indeed, but in retrospect, I think I should drop this patch
altogether...

This option is really special, so I think a better solution would
probably to add a big fat comment above that option that basically
states that:

    # This option is not an option of Busybox, it canbe selected even
    # if Busybox is not enabled.

I'll do that in a follow-up series.

Thanks for the review! ;-)
