[pkg-go] Bug#987378: yara breaks golang-github-hillu-go-yara autopkgtest + ftbfs

Dear maintainer(s),

With a recent upload of yara the autopkgtest of
golang-github-hillu-go-yara fails in testing when that autopkgtest is
run with the binary packages of yara from unstable. It passes when run
with only packages from testing. In tabular form:

                            pass            fail
yara                        from testing    4.1.0~rc2-1
golang-github-hillu-go-yara from testing    4.0.4-1
all others                  from testing    from testing

I copied some of the output at the bottom of this report. The same error
can be seen to cause golang-github-hillu-go-yara to FTBFS on
reproducible-builds [0].

Currently this regression is blocking the migration of yara to testing
[1]. Due to the nature of this issue, I filed this bug report against
both packages. Can you please investigate the situation and reassign the
bug to the right package?

More information about this bug and the reason for filing it can be found 
on
https://wiki.debian.org/ContinuousIntegration/RegressionEmailInformation

With my Release Team member hat on, I have set this bug as
bullseye-ignore, as without yara migrating, the packages in testing
don't have a problem. So I really don't mind if this bug is fixed only
after the bullseye release.

Paul
