RE: Moving Target in the Makefile

I'm sorry, but I don't understand what you're trying to do, or what
you're asking for.

If you already have written all these $(INSTALL) rules, you could
change the value of the INSTALL variable from "install" to do the
compare first.

Or, you could write your own install script which did the compare first,
then invoked the real install, and set INSTALL to the name of your
script.

I feel like I'm not answering the question you're asking.  Maybe if you
provided a simple example I would be able to provide more help.
