Hi Mark, I fixed the build failure in https://github.com/google/oss-fuzz/pull/9718. Once it's merged and reaches ClusterFuzz OSS-Fuzz should close the issue.

I think it would be better if it was possible to turn off --no-undefined separately to make it easier to build elfutils on OSS-Fuzz (where I can't pass `--enable-sanitize-*`) and avoid build failures like that going forward. It was discussed in https://sourceware.org/pipermail/elfutils-devel/2021q4/004418.html but didn't go anywhere though. Thanks, Evgeny Vereshchagin
