Subject: [PATCH] Stop python from linking with system ncurses (#1672)
Python will look to link with libncursesw in preference to libncurses. Since
ncurses in spack is built without suffixes there is no libncursesw and
python will link to the system libncursesw for _curses.so and
_curses_panel.so, as well as libpanelw for _curses_panel.so.
This PR introduces a patch that simple removes the check for ncursesw in
setup.py and therefore sets `curses_library` to `ncurses`.
