Hi Jakub,

I checked the tools and write a draft patch. But I have a question before post
the PR. AFAIK, This bot is only used for checking patches and adding status in
patchwork. But it doesn't support sending a reply to developer, right?

For the selftest reminder, I think it would be good to let developer know
via email if the file is missing in Makefile. What do you think?

Here is the draft patch:
