* configure.in: change (and comment out) checks for pthreads

* macros/acx_pthread.m4: change pthread search (should be removed)
	* src/engine/guid.c: remove pthread code and just use a static buffer.
	  (pthread code is kept within some #ifdef's, just in case we decide to
	   put it back in later).
