Patch for Makefile for ncursesw

[IronBug]

This is not a big issue. It's an useful utility, but on some Linux distros there's no ncurses, just ncursesw. So make fails. Here I offer a lil patch for the Makefile. It works. Maybe it could be added as variant, if ncurses library is not found, or as second Makefile for unicode systems.
