 The archive created by libarchive is the pax Interchange Format as
 defined e.g. in the Single Unix Specification version 3. The archive
 correctly contains a pax Extended Header with the linkpath fields.
 This overrides the value used in the following ustar header.

 The value for the extension string is not used at all by GNU tar,
 bsdtar and star.
