Threads - at least for apache - is optional, because you can compile apache with different MPMs (see documentation). MPM_PREFORK for example does not use threads, it forks itself - as opposed to MPM_WORKER which is based on threads. So if you set threads, apache is compiled with MPM_WORKER, if not, MPM_PREFORK is used. If you are running a threaded apache, and you are choosing to use php as apache module (apache2 use flag) then php with threads is required.
