Instructions for building packages are out of date.

The instructions for building packages are out of date. Among other things they reference needing manifest-tool which fails to build from source when using the recommended make bin/manifest-tool, and attempting to build a package (sshd) results in the following output, suggesting that more steps than what currently exists in the documentation are required:

$ linuxkit pkg build .

That specifically is a separate issue, which was fixed in #3870

You don't actually need it to build most packages, but some of the other secondary tools use it, and possibly kernel build.
