That doesn't work with the current dependency tracking machinery; it
needs to know the list of files at automake time in order to include
the relevant .Po and .Plo files in the Makefile.

This is something we may be able to address once we have machinery in
place to emit GNU make-specific code, and this Makefile is required to
work with GNU make only.
