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
- dropping BR2_PACKAGE_GETTEXT selection
In addition, we now use BR2_SYSTEM_ENABLE_NLS instead of
BR2_ENABLE_LOCALE to decide if NLS support should be enabled or
disabled.
