I tested adding hashes for all license files for 5.9.1. It turns out, this breaks the 5.6.2
legal-info because there are files in common between the two versions, but with different hashes.

    $ make legal-info

    ...

In the case you have different license file contents, but with the same name, between different
versions of a package, how should this be handled?
