Description:
When compiling MySQL on recent macOS, we get:

/home/sgunders/mysql/include/my_thread_os_id.h:57:10: warning: 'syscall' is deprecated: first deprecated in macOS 10.12 - syscall(2) is unsupported; please
      switch to a supported interface. For SYS_kdebug_trace use kdebug_signpost(). [-Wdeprecated-declarations]
  return syscall(SYS_thread_selfid);
         ^
/usr/include/unistd.h:733:6: note: 'syscall' has been explicitly marked deprecated here
int      syscall(int, ...);
         ^

How to repeat:
N/A

Suggested fix:
Use pthread_threadid_np() instead.
