cross deb fails.

[vi]

$ cross  deb 
error: no such subcommand: `deb`

	Did you mean `doc`?

$ cross  --version
cross 0.1.14
cargo 1.29.0-nightly (6a7672ef5 2018-08-14)

Although cross deb shows the similar message as cross deb1234, it takes longer to run, so maybe it tries... Do I need to somehow install cargo-deb inside the container?

How do I actually use cross deb? In any case the error message if cargo deb fails inside container should be customized by cross somehow.

In case someone hits this in search (or for you if you haven't solved this), the solution is in mmstick/cargo-deb#99
I've tested it and it works, but you do need to install some cross compilation tools onto your system and add overrides in .cargo/config.toml

This is now a duplicate of #716 (the more general solution).
