fixup! [ATFE] Ensure dependency on multilib-yaml as script expects the file.

The script that performs the common header generation
assumes the multilib YAML file is already generated.
This change adds an explicit dependency on the multilib-yaml
target to ensure the file exists before the common header
generate step is triggered.
