But of course. It is ncurses that drags it in. That figures ;)
It can be disabled in the configure script
     --disable-database      do not use terminfo, only fallbacks/termcap
So all it should take is to create a .bbappend and update EXTRA_OECONF.
But I might be wrong of course. Might be an even easier solution.
