They were rebuilt to test the autobuilders which had had a major
architectural change and upgrade (to make them more resilient and faster).
They were rebuilt from the same source code, no patches have been applied.
The resulting binaries should be the same modulo timestamp changes.

As these are just used for debugging, they are not tightly versioned.
Indeed we work on the assumption that all and any of them are
regenerable should they get lost for any reason (disk issues etc).
