Well, that's because I didn't realize that LZ4 might be set to
something that doesn't work at all. So Michael's thing worked, but
because it (in my view) fixed the problem in a more surprising place
than I would have preferred, I made a commit later that turned out to
break the buildfarm. So you can blame either one of us that you like.

Thanks, Michael, for preparing a patch.
