+Subject: [PATCH] KWIML tests: Remove format-security from flags
+
+For the tests where "format" is removed from flags, "format-security"
+should be removed as well. Otherwise building cmake with
+"-Wformat -Wformat-security" fails:
+
+| cc1: error: -Wformat-security ignored without -Wformat [-Werror=format-security]
