[flang-commits] [flang] flang: Fix build with latest libc++ (PR #127362)

LGTM.

I think Flang should figure out why they're not linking against libc++ since that will break other stuff in the future. But in the interest of fixing the current state of trunk, this patch works and doesn't make anything worse than it already is.
