  Log Message:
  -----------
  configure: Check for more specific function to pull in pthread library.

On my laptop, pthread_create() is always available without -lpthread, but
when I use -fsanitize=address, -lpthread is required to pull in other
threading functions such as pthread_rwlock_tryrdlock().  Thus, with
-fsanitize=address I have to manually add -lpthread to link commands one
way or another.  This commit avoids that problem by checking for a
function that is sometimes only available in -lpthread.
