> Changes since v1:
>  - use call github to build source URL
> Changes since v3:
>  - fix help indentation in Config.in
>  - use HOST_GO_TARGET_ENV as a base for build env vars
>  - cleanup build commands
>  - cleanup GOPATH and vendor directory setup
>  - Remove selections for graph drivers. Docker will gracefully degrade
>    at runtime to the best available graphdriver. It is unnecessary to
>    disable these at build time, or to pull in any other dependencies
>    like aufs-util or btrfs tools. The daemon will use whatever is
>    available at runtime.
> Changes since v4:
>  - remove commit hash from version scheme
> Changes since v5:
>  - re-introduce graphdriver selections
>  - these selections are required for btrfs and devicemapper
>  - there are buildtime dependencies on headers.
>  - bump to v1.12.0-rc3
>  - remove hack/vendor.sh call, it is unnecessary, dependencies are
>    pre-vendored into the source tree.

I had an error during install, dockerd needs to be installed only if it is
selected by BR2_PACKAGE_DOCKER_ENGINE_DAEMON.

Otherwise:
