[Reproducible-builds] Bug#826700: strip-nondeterminism: missing Multi-Arch: foreign, breaks cross building of gdbm

[Helmut Grohne]

Package: strip-nondeterminism
Version: 0.018-1
Severity: normal
Tags: patch

Hi reproducible folks,

gdbm started Build-Depending on strip-nondeterminism. Since that package
is Arch:all + Multi-Arch:no (implicitly), the Build-Depends is never
satisfiable in a cross compilation setting.

There are two ways to fix this:
1) Mark strip-nondeterminism Multi-Arch: foreign.
2) Remove Build-Depends: strip-nondeterminism from gdbm.

There are strong clues that the first option is correct:
 * strip-nondeterminism essentially does the same as
   dh-strip-nondeterminism and the latter is a dependency of debhelper,
   which is Multi-Arch foreign. So from the perspective of most packages
   the functionality of strip-nondeterminism is implicitly treated as if
   it were Multi-Arch: foreign already.
 * strip-nondeterminism is architecture-independent and uses only
   architecture-independent perl modules. It does not have maintainer
   scripts either (which would have been a common source for being not
   Multi-Arch: foreign).

I therefore attach a patch to add that marking. If you disagree, please
reassign this bug to src:gdbm to have that Build-Depends removed.

Helmut
