Maybe we should add a generic low overhead panic function. It should 
uniquely identify the error source. For this we could use the return 
address of a panic helper. For example:

RTEMS_NO_RETURN void rtems_game_over( void )


   rtems_fatal( RTEMS_GAME_OVER, (uintptr_t) __builtin_frame_address( 0 ) );
