Bug description:
When compiling with a recent version of GCC and enabling undefined sanitizer, I see the following warning:
./Modules/faulthandler.c:49:11: warning: "_Py_NO_SANITIZE_UNDEFINED" redefined
49 | # define _Py_NO_SANITIZE_UNDEFINED __attribute__((no_sanitize_undefined))
| ^~~~~~~~~~~~~~~~~~~~~~~~~
./Modules/faulthandler.c:44:13: note: this is the location of the previous definition
44 | # define _Py_NO_SANITIZE_UNDEFINED __attribute__((no_sanitize("undefined")))
| ^~~~~~~~~~~~~~~~~~~~~~~~~
The conditions just need some updating to match recent GCC and Clang versions.
