Take a look how Jerry Stueve has handled creating the various fake-language
files (pirate, Swedish chef, pig-latin, etc.) from the English file.  See
config/Makefile.am for the pattern to follow.  Jerry's original attempt to
do this broke non-GNU make builds, as it used a make target that is set
differently in GNU make than it is in other system makes.  ($<, as I recall,
which in BSD make is only set if the dependencies have wildcards, but is
always set in GNU make.)
