Subject: [PATCH] Add check of ncurses*-config

The recent ncurses package provides ncurses*-config program to give the
proper cflags and libs.  Let's use them if available.

Right now, the ncurses version (5) is hard-coded.  It should be better
to be variable as well, but it'd be messy.  Hope the ncurses version won't
change rapidly.
