Not a very strong reason.  Checking for pthreads is a little tricky,
but hardly rocket science.  These checks (from JACK) work for quite a
few platforms, though I'm sure there are others one could add...

AC_CHECK_HEADER(/usr/include/nptl/pthread.h,
	[CFLAGS="$CFLAGS -I/usr/include/nptl"])

AC_CHECK_FUNC(pthread_create, [],
    AC_CHECK_LIB(pthread, pthread_create, [],
	AC_MSG_ERROR([*** JACK requires POSIX threads support])))

There is also a conditional check for pthread_barrier_init().
