Nope, the regression is caused by something starting to pull in
the separate libtest-simple-perl package.

The test script breaks with newer versions of Test::More. We don't see
it in builds because it only gets run when AUTOMATED_TESTING=1, which
is the case with pkg-perl-autopkgtest but not with regular builds.

It looks like Test::More is internally counting the test cases it has
seen, but threading breaks this with newer versions of Test::More.
This is not supposed to happen: Test::More et al advertise multiple
thread support.

I haven't managed to distill it down to a simple test case. I suspect
it's something to do with the way SDL XS code uses threads.

For now, I suggest we set AUTOMATED_TESTING=0 in
debian/tests/pkg-perl/smoke-env, even if that's somewhat unsatisfactory.
