Port to GNU/Linux systems with tinfo but not ncurses.

* configure.ac (USE_NCURSES): New symbol.
* src/dispnew.c (init_display): Depend on USE_NCURSES, not GNU_LINUX,
to decide whether ncurses is being used.  Without this change,
GCC complains about tgetent not being declared, on a system
that has tinfo installed but ncurses not installed.
