I was about to sent this as a comment in bugzilla. See below.

I discussed this problem with Kristian on IRC on Wed. We don't need to 
change configure. Just protect the K_OFF code with an #ifdef and 
fallback to K_RAW in case it is not defined or the ioctl fails. In the 
fallback case, we also need to restore the on_tty_input() function for 
discarding the data on the tty.
