+Subject: [PATCH] introspection.m4: prefix pkgconfig paths with
+ PKG_CONFIG_SYSROOT_DIR
+
+We can't use our tweaked introspection.m4 from gobject-introspection tarball
+because gstreamer also defines INTROSPECTION_INIT in its introspection.m4, which
+is later supplied to g-ir-scanner.
+
+Upstream-Status: Pending [review on oe-core list]
