bpo-45405: Prevent internal configure error when running configure with recent versions of clang. (GH-28845) (GH-31889)

Change the configure logic to function properly on macOS when the compiler
outputs a platform triplet for option --print-multiarch.
The Apple Clang included with Xcode 13.3 now supports --print-multiarch
causing configure to fail without this change.
