If you call open with three arguments, "-" has no special meaning and
refers to a file named "-" (since the whole point of three-argument open
is to remove all magic interpretations of the filename string).  The
easiest way to work around this is probably to change the Automake helper
functions that sit between the code and the Perl open command and have
them switch to calling open with two arguments if the file name is "-".
