No thanks.  Patching Makefile.am at least stands a chance of applying
correctly across multiple releases of the package.  Worse, patching the
generated files stands a good chance of missing an instance of whatever
you were patching for when the next release comes out.

Packages change version much more often than libtool changes version.
I'd rather go with the method that's resilient against the more common
change.
