@micmac1: I did it because after merging your PR, I got usage message on macos:

``` $ python3-config --ldflags --embed Usage: /opt/local/bin/python3-config [--prefix|--exec-prefix|--includes|--libs|--cflags|--ldflags|--extension-suffix|--help|--abiflags|--configdir] ```

I change it and no usage printed:

``` $ python3-config --ldflags --embed 2>/dev/null ```
