Building Linux wheels seems to be broken

Yeah, I've seen that before. IIRC the version of auditwheel is tightly tied to wheel and you can't upgrade wheel in the docker image without having this issue.

We should perhaps move on to the manylinux2010 image anyway (which still has this issue, but at least has a newer compiler). It will still generate manylinux1 tagged wheels if possible.

This looks like pypa/auditwheel#102, filed in 2018, so how come we haven't seen this problem before now?

The release of persistent 4.4.2 from August 2018 has manylinux wheels; the release of persistent 4.4.3 from the end of October 2018 (after the release of wheel which broke auditwheel) does not. So we have had the problem before, we just didn't notice.
