+       move-if-change: cope with concurrent mv of identical file.
+       * build-aux/move-if-change (CMPPROG): Accept environment
+       variable as an override for `cmp'.
+       (usage): Document CMPPROG.
+       Adjust comparison to drop stdout.  Cope with failure of mv if
+       the target file exists and is identical to the source, for
+       parallel builds.
+       Report from H.J. Lu against binutils in PR binutils/12283.
