Comment:

 After conversation with Erik, we came to the conclusion that it seems we
 need two files to indicate the two different things we need. We need one
 file to indicate that the thorn is done, and whose date only updates if
 something in that thorn was updated (done), and we need another file that
 indicates that the library in external thorns is available, either built
 or available otherwise. The date of that file has to update whenever that
 library changed (when built). That second file can be considered
 'internal' to that thorn. We considered two possible names for that file:
 build_unnecessary_or_complete or available. If no objections are raised
 and no other names are proposed, it will be 'available'. This will need to
 be changed in all external libraries, and is a release-blocker because
 currently libraries are built even if they are supposed to not be.
