Compile without X11 headers

[auriocus]

ADSupport requires X11 under Linux. Although this is only needed for xwindow.c in GraphicsMagick. This is especially inconvenient for cross-compiling. I seriously doubt that anyone uses it anyways. Attached is a small patch that switches off X11. Another patch must be applied to ADCore then simultaneously. Hence, not a pull request.
