[issue44689] ctypes.util.find_library() does not find macOS 11+ system libraries when built on older macOS systems

Gregory Szorc added the comment: I spoke too soon: you can reproduce this with CPython's build system and I think this is a legit regression. I think the function sniffing logic is subtly wrong. Here is the logic as written: #ifdef __APPLE__ #ifdef HAVE_DYLD_SHARED_CACHE_CONTAINS_PATH
