MAKEFILES will always be empty in all versions, unless you set it.
That's a user-defined variable.

Not really; not in versions before 3.80.

 1) Don't use constructs like the find above; instead use something

        rm -f $(OBJECTS)

 2) Set a variable in the Makefile which has the path of the directory:

        THIS = some/dir
                find $(THIS) -name \*.o | xargs rm -f
