Hmm, no simple way no. And you really shouldn't bother too much with it anyway
in the hope people use package managers :)

But if you want a way (assuming you have something like data files that you parse
as *):

install-data-hook:
	cd $(DESTDIR)$(mydatadir) ;\
	for file in *; do \
		if ! echo " $(mydata_DATA) " | grep -q " $$file "; then \
			echo rm $(DESTDIR)$(mydatadir)/$$file ;\
			rm $$file ;\\
		fi ;\
	done

you see: you don't really want that. You should prefer marking your data with a version
and ignore in the program those of an older version.

Greetings, Stephan
