happens this patch enables building and execution of Xorg server on ARC.

+Subject: ARC: Add support for ARC architecture
+
+Xorg server could be built for and run on Synopsys DesignWare ARC cores.
+These changes are required for successful building and execution of the server.
+
+Both little-endian and big-endian flavors of ARC cores are supported.
