 I've added options to touch(1) to make it easy to test this sort of
 thing by randomizing the order of files' timestamps with a pipeline
 find /usr/src -type f -print | shuffle -f - | touch -i -d -5 -
 (though I actually saved find's output, and inserted a tee between
 shuffle and touch).
 I've done two test builds with randomized timestamp order.  Each of
 them ran into the* issue mentioned in the PR; with those
 touched, they fell over with cryptic messages while building gcc.
 The touch(1) source I used, and the results, are up for FTP.  (They are
 big - the list of source files is about four megs and the build log is
 between one and two - so I don't want to dump them in the PR directly.)
 See (there's a README
 there describing the layout).
