I looked at this in more detail.  The problem happens before libtool is
even invoked, which is why max_cmd_len doesn't appear to make a difference.

make is trying to invoke libtool with all of the dependencies.  If that
invokation were successful, which it isn't, libtool would then do the
correct partial link.  But it doesn't get that far.  I think something
needs to tell automake about max_cmd_len also so that it does not cause
make to exceed the maximum length.  I'm not entirely sure how this would
work though, because it seems like it might mean requiring automake to
know about partial links also.
