Describe the bug

When using an x86_64 Mac with Python 3.12 (or 3.9), it is not possible to build the stub app in the Mac OS app template.

Steps to reproduce

  1. Download the briefcase macOS Xcode template
  2. Run briefcase create macOS Xcode in the stub directory
  3. Run briefcase build macOS Xcode in the stub directory
  4. See the following error 
    Undefined symbols for architecture x86_64:
"_mkfifoat", referenced from:
  _os_mkfifo in libPython3.12.a(posixmodule.o)
"_mknodat", referenced from:
  _os_mknod in libPython3.12.a(posixmodule.o)
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
note: Using new build system
note: Planning
