Thanks for the report. Fixed as follows:
2017-01-31 Bruno Haible <address@hidden>
lock: Fix link error (regression from 2017-01-05).
* lib/glthread/lock.h [USE_POSIX_THREADS_WEAK]: Declare also
pthread_rwlockattr_init, pthread_rwlockattr_setkind_np,
pthread_rwlockattr_destroy weak.
Reported by Tom G. Christensen <address@hidden>.
