Disable the use of std::call_once on OpenBSD with libstdc++.

It was noticed this caused performance regressions and deadlocks. PR30768.

Reorder the code to make it clearer what is tested.

PPC now disables the use of std::call_once only with libstdc++ with
the reordering of the code, as was the original intent.
