Compile for macOS 64-bit

[shoogle]

With the release of Catalina (macOS 10.15), Apple dropped support for 32-bit binaries. This means the "universal binaries" in the official OpenArena 0.8.8 Unified Zip no longer work on macOS.

I'm working on creating x86_64 binaries for macOS over at shoogle/OpenArena-legacy. Any help would be greatly appreciated!

So far the game compiles and the main menu launches, but it crashes when you actually try to enter a game. See my README for details.

Hello @shoogle ! I am interested in trying your build for Mac os 11.6. The artifacts in your project say they have expired. Maybe try to host them somewhere more long term? Artifacts of builds tend to last about 30 to 60 days.

Thanks for your efforts! Looking forward to playing this gem at the next work lan party :)
