Merge #767

767: Add cross-dev and cross-util commands. r=Emilgardis a=Alexhuszagh

The cross-dev command has the `target-info` subcommand, which target information (libc, compiler, C++, qemu version) for a given target.

```bash
cross-dev target-info
cross-dev target-info arm-unknown-linux-gnueabihf
```

The cross-util command has the `list-images` and `remove-images` subcommands. `list-images` lists all cross images, including local development files. `remove-images` removes cross images.

```bash
cross-util list-images
cross-util remove-images
cross-util remove-images arm-unknown-linux-gnueabihf
```

Closes #760.
