Bug#967059: lintian: Do not issue package-contains-no-arch-dependent-files for packages with arch-dependent dependencies

[Peter Wienemann <fossdev@posteo.de>]

Package: lintian
Version: 2.86.0
Severity: normal

Dear Lintian maintainers,

Lintian issues the tag package-contains-no-arch-dependent-files on
packages without "Architecture: all" if they only contain
architecture-independent files (at least this is my understanding).
That is fine unless they have architecture-dependent dependencies
(i. e. arch-dependent "Depends:" entries). In the latter case making
the package architecture-dependent is required to implement
architecture-dependent dependencies even though the package contents
is purely architecture-independent (see Debian Policy Manual
section 7.1).

Best regards,

Peter
