It's better to write src/language/lexer/q2c$(EXEEXT_FOR_BUILD)
here than to write $@, because non-GNU makes do not necessarily
support $@ other than in implicit rules.  We do depend on some
GNU make features elsewhere, but I'd prefer to keep the
dependencies to a minimum so that we have a better chance of
being able to eliminate them one day.
