Build of openmpi on macOS, apple-clang@15.0.0 fails

[srherbener]

Describe the bug
When building on macOS with apple-clang@15.0.0, the autoconf configure step fails with this error message:

Note that openmpi builds just fine with apple-clang@14.0.3 and earlier versions.

Additional context

Have you checked the spack (mainline) issues and PRs? Also, the spack slack channel. Maybe that's been fixed there already. We (JCSDA) have more urgent things to do at the moment (technically still in "reduce tech debt sprint"), so that will need to be put on the backburner if it's not been solved in spack mainline already.
