+Subject: [PATCH] Filter out LTO build options from the perl ccopts
+
+Kernel tools currently does not build with LTO options enabled. We can
+turn off the option in most places through the spec file, but for the
+perl bindings, it auto detects what perl was built with and uses those.
+This patch will filter out the lto options allowing kernel-tools
+packages to build correctly. I expect this patch to go away when the
+LTO issues are worked out upstream.
+
+Upstream Status: Red Hat only
