__SANITIZE_UNDEFINED__
https://gcc.gnu.org/ml/gcc-patches/2019-09/msg01286.html
GCC upstream does not see value in feature parity with LLVM sanitizers.
For the time being this will be a NetBSD specific extension.
__SANITIZE_LEAK__ is needed for __NO_LEAKS in <sys/cdefs.h>
__SANITIZE_UNDEFINED__ is planned to be reused in the kernel headers.
