Thanks, but we don't actually install anything under
$(STAGING_DIR)/usr/include/ncurses (it is directly in
$(STAGING_DIR)/usr/include). Looking at the configure script, the
documented way of not adding a special -I for ncurses is simply to pass
--with-ncurses-include-dir=none so I've changed it to use that instead.
