Bug#921573: lintian: binary-from-other-architecture only works sometimes

[Helmut Grohne <helmut@subdivi.de>]

Package: lintian
Version: 2.5.124

Please cross build the procmail package for arm64 and for mips64el on an
amd64 build machine. In both cases, you'll get a successful build, but
the binaries inside the package are amd64 binaries despite the
arm64/mips64el architecture tag. As such, lintian should emit tags:

| E: procmail: binary-from-other-architecture usr/bin/formail
| E: procmail: binary-from-other-architecture usr/bin/lockfile
| E: procmail: binary-from-other-architecture usr/bin/procmail

For the broken arm64 cross build, these tags are correctly emitted.
However, the broken mips64el build is not recognized as broken by
lintian. The binary-from-other-architecture tag is strangely missing
there.
