Bug#969726: Please make autopkgtests cross-test-friendly

[Sebastien Bacher]

Package: poppler
Version: 20.09.0-2
Severity: minor

Dear maintainers,

In Ubuntu, we are in the process of moving the i386 architecture to a
compatibility-only layer on amd64, and therefore we are also moving our
autopkgtest infrastructure to test i386 binaries in a cross-environment.

This requires changes to some tests so that they are cross-aware and can
do the right thing.

The poppler tests currently fail in this environment, because they are
build tests that do not invoke the toolchain in a cross-aware manner. 
I've verified that the attached patch lets the tests successfully build
(and run) i386 tests on an amd64 host.

Note that upstream autopkgtest doesn't currently set DEB_HOST_ARCH so
thisis a complete no-op in Debian for the moment.  Support for
cross-testing in autopkgtest is currently awaiting review at
https://salsa.debian.org/ci-team/autopkgtest/merge_requests/69 and once
landed, will still have no effect unless autopkgtest is invoked with a
'-a' option.  So this change should be safe to land in your package
despite this not being upstream in autopkgtest.


Thanks for considering,
