Glibc on Linux does the same for things like pthread_mutex_lock:
$ cat z.c
#include <pthread.h>
int main()
{
if (pthread_mutex_lock(NULL))
return 1;
return 0;
}
$ gcc z.c # build without threads
$ ./a.out
$ echo $?
0
$ gcc -pthread z.c # with threads
$ ./a.out
Segmentation fault

Glibc doesn't provide no-op functions for things like
pthread_mutex_create, those are only available when the full threading
library replaces all the no-op functions.
