Attached are patches to add copies the X macros to xorg's util-macros
package and add a method to search via pkg-config. This isn't ideal
since it requires that the xorg macros are found to override the
autoconf ones, but I couldn't find a satisfactory way to wedge in a
pkg-config check to AC_PATH_X externally.

This approach has the advantage that we still fallback on the xmkmf and
direct approaches whether the xorg macros and pkg-config are available
or not. However, in the case that the xorg macros are available, we can
be smarter about using the X installation. It also makes sense that the
X implementation control the autoconf macros governing its usage.

Let me know what you think. I've cc'd the xorg list to see if this would
be acceptable.
