Having poked at this further, I think the best approach is not to try to
add any ABI kludges here, because as things stand you get a reliable
failure to resolve a symbol, whereas with the kludges, some combinations
fail with segfaults, and could conceivably misbehave in weirder ways.

So I think we just declare that you should use matching xapian-compact
and libxapian, at least for 1.0.x.  This is most relevant to people
who build binary packages, so I've started a page of advice for them
including this and a few other tips:

Feel free to add further packaging wisdom there.
