objects.inv not invalidated?

[JulienPalard]

Looks like /objects.inv (intersphinx thing) has not beed invalidated during the 3.10 release.

I grepped a bit in the logs, looks like we know how to invalidate objects.inv:

$ zgrep -h -o [^,]*objects.inv /var/log/docsbuild/* | sort | uniq -c | sort -gr

      4 3.10/objects.inv
      2 ko/3/objects.inv
      2 ko/3.9/objects.inv
      2 id/3/objects.inv
      2 id/3.9/objects.inv
      2 fr/3/objects.inv
      2 fr/3.9/objects.inv
      2 3/objects.inv
      2 3.9/objects.inv

so the issue may come from the lack of invalidation at link time: when we change the /3/ link, everything under /3/ should be invalidated, but currently nothing is.

We now purge symlinks (b3c3137efb04c789a60b4ceb65fbb0ad46370f4b).
