Thanks.  Let me try helping you understand what I think is the issue
here.

Suppose you are maintaining a Lisp package which includes a Makefile
used to byte-compile all the Lisp files as part of the installation
procedure of the package.  This Makefile has targets and dependencies
that build *.elc files from *.el files.  How do you modify the
Makefile to produce *.eln files during the build, while maintaining
the dependencies between the Lisp files? the dependencies would mean
that when file1.el is modified, you need to recompile not only that
file1.el, but also file2.el and file3.el.  How do you get new
file2.eln and file3.eln via Makefile rules in this case?

I hope I succeeded to explain the issue.
