This commit switches to use the new gettext logic, which involves:
- using TARGET_NLS_DEPENDENCIES instead of hand-encoded dependencies
on gettext/host-gettext
- using TARGET_NLS_LIBS to force linking against libintl. This wasn't
done so far, but is needed for the build to work, because uClibc
now has a stub gettext implementation, which is mistaken as being
the full gettext implementation by the configure script
- dropping BR2_PACKAGE_GETTEXT selection
