gettid is not a syscall which fails. From the gettid(2):
--------------
RETURN VALUE
On success, returns the thread ID of the current process.
ERRORS
This call is always successful.
--------------
Similarly, the code is written to rely on the documented behavior. So,
when it's not available, maybe the wrapper should return
(pid_t)pthread_self() instead of -ENOSYS?
