build system: create .xcompile dependency
It's probably safe to say that .xcompile needs an update if util/xcompile/xcompile changed, so tell make about this dependency. Updates are honored immediately due to GNU make's feature of reinterpreting everything when an included file changes. See "How Makefiles Are Remade" in the GNU make documentation for details.
