Sorry, I guess I said that on IRC but left it out of the email...

The failure is only with perl 5.22, and it doesn't matter whether it's
perl-native or the should-not-be-used-anyway build host perl (that's
what the patch is for).

It's only a warning in prior versions of perl, so you wouldn't see it
in either case above.
