[Qemu-devel] [PULL 6/6] curses: Use cursesw instead of curses

[Gerd Hoffmann <kraxel@redhat.com>]

From: Samuel Thibault <samuel.thibault@ens-lyon.org>

Use ncursesw package instead of curses on non-mingw, and check a few
functions.
Also take cflags from pkg-config, since cursesw headers may be in a
separate, non-default directory.
