Comment (by michaelld):

 I see this issue on my macOS 11 boot system as well, where the
 `QMAKE_MAC_SDK` is set to `macosx11`. I've debugged to the point of
 believing it's a difference between the SDK info installed into
 `/Library/Developer/CommandLineTools/SDKs/` and `xcrun --show-sdk-path` --
 which may or not be the same; for me this latter is
 `/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk`:

 I believe the logic in `portconfigure.tcl` needs to be updated for this
 sort of use case. That said, these are what I _think_ and _believe_ rather
 than have confirmed as a bug or fix.
