By end user, I mean person downloading and building the sources.

They are optional build depdendencies.  They are provided pre-built,
and won't be rebuilt unless they get outdated.  In the release
tarball, the timestamps are correct, ensuring this never happens.
When checking out with git, the timestamps are incorrect, and it
attempts to rebuild something that's *already built*.
