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.
