--- Comment #1 from Thomas Schwinge <tschwinge at gcc dot gnu.org> ---
I shall soon post "GCN, nvptx libstdc++: Force use of '__atomic' builtins
[PR119645]" -- which just hard-codes this, but doesn't resolve the (presumed)
underlying issue.
I've also re-discovered my own PR70560 "Review configure checks for
_GLIBCXX_ATOMIC_BUILTINS and atomicity_dir" (for x86_64), from almost a decade
ago. ;-)
