Yes, switching it to a pre-configure hook would fix it.
But that would be a one-off solution.

Providing it in the autotools-infra will allow us to have consistency
across packages and would allow us to fix it in a single place in the
future, rather than having to hunt down allow the offenders.

But as I said, this is an RFC, so we can discuss it further.

First, we have to agree we want it in the autotools infra or not.

Then, we'll have to check whether a boolean + an _OPT is enough, or if
we need something a bit more involved (e.g. let packages define the
complete hook, and just have the infra call it at the proper moment.)
