MDEV-9128 - Compiling on IBM System Z fails
Provided IBM System Z have outdated compiler version, which supports gcc sync builtins but not gcc atomic builtins. It also has weak memory model.
InnoDB attempted to verify if __sync_lock_test_and_set() is available by checking IB_STRONG_MEMORY_MODEL. This macro has nothing to do with availability of __sync_lock_test_and_set(), the right one is HAVE_ATOMIC_BUILTINS.
