readline.pc contains Requires.private=ncurses, even if readline is built with ncursesw. When a user of readline uses pkg-config to ask for the cflags, the lookup fails if ncursesw without compatibility with ncurses is used.
Fix it by ensuring that ncurses compatibility is enabled if readline is built with ncurses.
