    test-runner.sh: Log output: Use the testname.log, instead of /bin/err.log
    
    By using $2 instead of $1. Something about my current system seems to
    cause bash to be the $1 (the actual program that has taken the other args)
    instead of the test. I don't know what has actually changed in autotools.
    
    Obviously this is very fragile and should be fixed properly.
