That's normal.  I think more recent autoconf suppresses the message,
but I'm not sure.

Basically, this is because we abuse gdb's configure quite badly.  I
recommend that you build a small curses library or grab one from an
m68k disribution or what-have-you, and ignore the problem for now. 
I'll see about fixing this a little down the road.
