The new form matches the way we test for other weak symbols (for example in posixmodule.c)
I earlier moved the pragma, but not the comment that explains why it is necessary.

Fix a number of compile errors with GCC-12 on macOS: 1. In pylifecycle.c the compile rejects _Pragma within a declaration 2. posixmodule.c was missing a number of ..._RUNTIME macros for non-clang on macOS 3. _ctypes assumed that __builtin_available is always present on macOS (cherry picked from commit cdde29d) Co-authored-by: Ronald Oussoren <ronaldoussoren@mac.com>
