Macports only supports buidling against the sdk you would ‘naturally’ get
installing the Xcode/CLT version supported on a given OS. Whilst it might be
possible in a hacking way to install a newer SDK on alder OS, this is not
something macports can realistically support.
So no, macports only supports building for arm on macOS11 or newer.
