X Title: [3.9] gh-97897: Prevent os.mkfifo and os.mknod segfaults with macOS 13 SDK (GH-97944) by miss-islington · Pull Request #97968 · python/cpython

Description: The macOS 13 SDK includes support for the mkfifoat and mknodat system calls. Using the dir_fd option with either os.mkfifo or os.mknod could result in a segfault if cpython is built with the macOS 13 SDK but run on an earlier version of macOS. Prevent this by adding runtime support for detection of these system calls ("weaklinking") as is done for other newer syscalls on macOS. (cherry picked from commit 6d0a019) Co-authored-by: Ned Deily nad@python.org Issue: gh-97897
