If not, this is must be checked at link time, otherwise the entries
must be topologically ordered.

I don't see why a topological ordering is required. It suffices to resolve the relocations lazily on demand. Of course, a circular reference will cause an error or an infinite loop.

Humm, right. But better to detect this at link time rather than unexpectedly at run time.
