This is true for uClibc, but for other libc timer_notify is asigned to
the `sigev_notify_function` function which has an `union sigval` as
argument [1].

Snipped from the source code of timers_unix.c:

#if defined(__UCLIBC__)
	[..]
	signal(SIGALRM, timer_notify);
#else
	[..]
	sigev.sigev_notify_function = timer_notify;
	[..]
#endif
}
