Merged #55265 into this one, made ppc64le-specific. It's possible this is fixed.

This issue was fixed by https://go-review.googlesource.com/c/go/+/425355 due to an old gcc on the builder. I haven't seen it since then. I left the issue open due to the old distro on the builder but maybe that problem needs a different issue.
