Generic language configuration

Some of the repos I wish to manage with Travis actually involve dozens of programming languages. Now, I’m happy to customize the packages and scripts to suit my needs. But I would like a clear way to indicate this in the language key, such as language: "" or language: "none", language: "generic", or similar enum value. Can we please get an option for this?

Use language: generic (or even language: minimal if you don’t need the additional preinstalled software).

If you need to distinguish your jobs with a marker other than the OS + language + language version + envvars (this is usually sufficient), you can manually name: them.
