    tests: Unconditionally enable verbose debugging output from tests
    
    Since we now require the automake-1.12 parallel test harness, we can
    take advantage of the fact that it only outputs tests’ debug spew if
    they fail. That means tests can now unconditionally output everything,
    which should simplify debugging.
