Re: --enable-depend by default (was Re: Patch: fix lock contention for HASHHDR.mutex)

Alternately the buildfarm could be changed to retain earlier builds and use
dependencies to reduce build times. This would have the benefit of
detecting dependency failures. At the expense of a lot more noise, at least
until we Orrin out whatever dependency failures are there now.

Or we could add extra rules so that if you don't configure with
dependencies we check for unclean builds and error out. This would make at
least accidental unclean builds much led likely.
