    Hmm, for ELF-based systems, one could try to use ELF symbol versioning
    instead of a hash-code and since that is already part of the current
    binutils it should not be a problem. The question however is if that
    is sufficient for our purposes? Could someone with more understanding
    how module versioning works comment on this?
