LP, this was unfair to reverse-pass me :-) Anyway - done - thanks Julian and James C. for your work on that.

Now, the filter is architecture-specifc, so you can't just rewrite the addresses, so the safest bet is to just return an error here. I guess you should just return EINVAL, but not sure. I'd really like something that can be identified, so seccomp errors can be ignored when it's not supported.
