autogen: Fix placement of config autogeneration

- Autogenerate test configurations _before_ macro typo check.
Otherwise, a typo in the main config that has spread into the
derived configs cannot be fixed by fixing it in the main config
and re-running autogen: It will fail at the macro-typo check
stage before having updated the derived configurations.
