+Subject: [PATCH 1/1] Fix config.mak.uname to allow cross-compilation
+
+Current implementation imperatively sets variables from "uname" output.
+This breaks cross-compilation because uname is run on host while target
+configuration may be different.
+
+Make current behavior a non-imperative default, so it's possible to
+force different values setting make variables.
+
+To cross-compile it will be necessary to explicitly set the various
+uname_X variables to values compatible with target.
+No change is needed with normal host compilation.
+Patch is trivial.
