(cherry picked from commit 94e08f7)

During the refactor we forgot one more place where the `flag_values` on
the platform information was used. They were no longer populated and
broke.

The solution is to use `selects.config_setting_group` to maintain
behaviour and in order to smoke test I have added a target to verify
that the aliases work.
