+Subject: [PATCH] configure.ac: invert order for wayland-scanner check
+
+When cross-compiling the .pc file might point to the wrong
+wayland-scanner binary (target rather than host) resulting in a
+non-executable and wrong scanner.
+Try searching the PATH first, and if that fails fall back into
+pkg-config.
