Jacana seems to be using 5.8.8 according to $Config{version} (though
5.26 is in PATH, strangely); fairywren is 5.30.
Bowerbird is 5.16.2 and Drongo 5.24.3.
I don't think the buildfarm tells us about Perl internals to know if
they interpret platform-dependent newlines differently.
I suppose the difference might be the way Perl interprets the literal
newline embedded in the regexp, versus how the log file is written.
With the [\r\n]+ pattern the platform schizophreny no longer matters.
