The best way to know would probably be asking the person(s) that have
written such a line :-)

My initial "knee-jerk" guess was that that line was needed for older automake
versions, but by looking into the automake history, I've seen that the automatic
remake rules for files depending on config.status have been around in a form or
another since February 1996 (i.e., pre 1.0).  So I don't honestly know what the
rationale for that line is.
