+build: always build wayland-scanner
+
+The previous idiom for building a cross-compiled Wayland is to build once for
+the build host (with --enable-scanner --disable-libraries) to get a
+wayland-scanner binary that can then be used in a cross-compile (with
+--disable-scanner).  The problem with this is that the cross wayland is missing
+a wayland-scanner binary, which means you then can't do any Wayland development
+on the target.
+
+Instead, always build wayland-scanner for the target and change
+--enable/disable-scanner to --with/without-host-scanner.  Normal builds use the
+default of --without-host-scanner and run the wayland-scanner it just built, and
+cross-compiled builds pass --with-host-scanner to use a previously built host
+scanner but still get a wayland-scanner to install.
+
+(a theoretically neater solution would be to build two scanners if required (one
+to run and one to install), but automake makes this overly complicated)
