Comment:

 It is already possible to build opencv4 on arm64. But what is not
 possible, as you note, is to build it universal. The port deliberately
 disables the universal variant. This has been in the port ever since it
 was added. Perhaps it was found not to work, or perhaps it works fine and
 was just never tested. If you like, you can try to remove that line, and
 if it works, or if it doesn't work and you can figure out what else needs
 to be changed, you could submit the fix to us.
