The `sched_yield()` function was originally included to facilitate the of POSIX_REALTIME and POSIX_THREADS_EXT Option Groups in Issue 5. It was then marked as part of the _POSIX_PROCESS_SCHEDULING Option in Issue 6, but then was not clearly marked as part of the POSIX_THREADS(_BASE) Option Group until Issue 7. Moving it to `pthread.c` (and making it a function with regular linkage rather than inline) ensures that it will be available with the `POSIX_THREADS` Option Group. For more information, please see `POSIX_THREADS_BASE` in https://pubs.opengroup.org/onlinepubs/9699919799/xrat/\ V4_subprofiles.html and https://pubs.opengroup.org/onlinepubs/9799919799/xrat/\ V4_subprofiles.html Signed-off-by: Chris Friedt <[email protected]>
