If you write a rule like:

        foo bar biz : fee fie foe

then make interprets that to mean EXACTLY the same thing as:

        foo : fee fie foe
        bar : fee fie foe
        biz : fee fie foe

This explains your problem, I believe, since every target in
$(EXPORTED_HDRS) lists ALL the files in $(EXPORT_HDRS) as a
prerequisite, and so will be considered out of date if ANY file in
$(EXPORT_HDRS) is newer, and each target will be updated.
