From: David M. Syzdek <david.syzdek@acsalaska.net>
Sets the value of PTHREAD_LIBS to the correct flags for linking pthreads on the current environment. If the correct flags can be determined then THREADED_DELTA_SEARCH is set. If the correct flags cannot be determined, then THREADED_DELTA_SEARCH is unset.
