How about this: when you find FOO += bar but FOO is not initialized,
replace it with FOO = @FOO@ bar.  It would probably cover the most
interesting cases, no?  Hmm...  Not the case of DEFS :-(

How about adding a mark, such as @+FOO@, that you'd replace with
the contents automake would set by default, when it gets to the point
of setting the defaults?
