+MGA DDX: make it possible to find EXA support
+Newer versions of the xserver stricter requirements on header order
+which caused the configure tests for EXA support to erroneously fail.
+Since XAA was already removed from an earlier version of xserver, the
+configure failure meant no acceleration was possible. Patch configure
+tests similar to r128.
