error message diff with Perl 5.22.0

With the recently released Perl 5.22.0, the tests fail thus:

-ERROR: Global symbol "$global" requires explicit package name at line 3.
-Global symbol "$other_global" requires explicit package name at line 4.
+ERROR: Global symbol "$global" requires explicit package name (did you forget to declare "my $global"?) at line 3.
+Global symbol "$other_global" requires explicit package name (did you forget to declare "my $other_global"?) at line 4.
CONTEXT: compilation of PL/Perl function "uses_global"

With PL/Python, this happens for just about every other release, and we usually add another expected file. I don't see anything like that for PL/Perl yet. Should we add a new expected file, or is there a different preferred solution?
