I kicked off the build, but it was only successful for F37 (all arches), EPEL8 (all arches), and EPEL9 (all arches). Failed on F38 (all arches), F39 (all arches), Fedora rawhide (all arches), and EPEL7 (all arches). Logs are here for review: https://copr.fedorainfracloud.org/coprs/vbatts/bazel/build/6550571/
