Lucas, would you be interested in this (archive rebuild with gcc-4.6
as gcc)?  If so, is there anything I can do to help, aside from
looking over the result, writing scripts to categorize failures, and
filing bugs if there is consensus after a report on debian-devel?

Sorry, that was unproductive of me.  In certain cases (e.g., binutils)
it is worth a failed build now and then to get a reliable result.
