You don't seem to add a ncursesw5-config -> ncurses5-config symlink, but
we explicitly refer to ncurses5-config in several places (and some
configure scripts probably also expects it):

package/alsa-utils/alsa-utils.mk:       ac_cv_prog_ncurses5_config=$(STAGING_DIR)/bin/ncurses5-config
package/dialog/dialog.mk:DIALOG_CONF_OPT += NCURSES_CONFIG=$(STAGING_DIR)/usr/bin/ncurses5-config

What's with this extra whitespace? I see it gets fixed up in patch 2,
but we might as well do it right in patch 1 instead.
