Ideally I guess I would use https://github.com/thegeeklab/drone-docker-buildx or something similar to build for multiple platforms.
This isn't just an efficiency/neatness change - if you try to `git commit` when there's nothing to commit, the command will return `1` which will be parsed as an error, and thus the whole build will be categorized as a failure.
Next steps: * Update other repos to use this * Blog about it :P
