Additional context

The CMake file that TIC-80 uses to build mruby calls the xcrun command to find the macOS SDK, using the deprecated exec_program CMake command to do so. Nixpkgs is using a fake xcrun command from xcbuild, which outputs warning: unhandled Platform key FamilyDisplayName before returning the SDK path. exec_command captures both stdout and stderr in the same variable, causing the warning to end up in the Makefile and breaking things.

I've just submitted nesbox/TIC-80#2869 to replace the exec_command call with execute_process, the recommended replacement. execute_process handles stdout and stderr separately, so it doesn't have this problem.
