[PATCH 4/8] tags: look at $(am__tagged_files) to decide whether to activate

[Stefano Lattarini]

This is just a preparatory refactoring in view of future changes.

* automake.in (handle_tags): To decide whether to include the tags rules,
rely on whether the automake-defined variable $(SOURCES) is non-empty,
rather than on the fact that '&saw_sources(1)' returns true.
