I think the issue here is similar to https://gitlab.alpinelinux.org/alpine/aports/-/merge_requests/89101 - Bazel is building a vendored version of abseil that is so old it no longer builds with recent gcc. We should modify the bazel build definition to use the system-provided abseil instead, which was recently updated in Alpine.
