I looked into the failure mentioned in this bug (as well as two other failures on !amd64), and committed the following patch in Ubuntu, which solves all outstanding issues and gets autopkgtests passing on all six of our architectures again:
http://launchpadlibrarian.net/396411616/lintian_2.5.111ubuntu1_2.5.111ubuntu2.diff.gz The changelog explains which upstream commits regressed these three tests, and the fixes should be fairly obvious using those commits as references. I will note that this doesn't fix files-multiarch-foreign-files to work on other arches, it just restricts it to amd64, but that's the state it was in before debian bug #886163 was regressed. I suspect it would be more "correct" to figure out why that test doesn't pass on other arches as it might mean the check also doesn't work on other arches, but for now, it seemed that reverting to the pre-regression behaviour was the path of least resistance. ...
