Good question, we're not doing a very good job of documenting this.

And I'm not sure what would be the best way to do it.

A reasonable thing to do would be to put a note on the relaese
downloads page. But I'm not even sure what to put there.  "OpenMP kind
of works on AArch64", what does that mean to a user?

It also comes back to what the nature of the release is. For me, it's
a periodic best-effort-stability snapshot of what we've got, which
packagers and other downstream folks build on.
