Bad things will happen if libx264 wasn't build with pthread in it.
At least from the Makefile in //extras/contrib/src it seems a

So I would move that to the x264 section and detect if libx264 was
static linked with pthread and set the flag as appropriate ( or error
out if it doesn'nt make sense to use x264 without pthread)

I would do something like
AC_CHECK_LIB(pthread_win32_process_attach_np, x264,
