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().
