+Subject: perf python: Allow checking for the existence of warning options in clang
+
+From: Arnaldo Carvalho de Melo <acme@redhat.com>
+
+commit b81162302001f41157f6e93654aaccc30e817e2a upstream.
+
+We'll need to check if an warning option introduced in clang 19 is
+available on the clang version being used, so cover the error message
+emitted when testing for a -W option.
