Bug#118908: make TAGS does not work without having run configure

Here is a patch to use the old behavior when the repository is
configured and to use the new, simpler behavior, when the repository
is unconfigured.

This also fixes a bug in the TAGS target: currently, we generate TAGS
files even in directories marked as broken (i.e. with the dir/BROKEN
marker).

One bug, however, remains: libstore/parted.c causes the TAGS target to
fail as there is no parted.d and, might I add, it fails for good
reason: we never actually create a parted.d file.

        * Makefile (TAGS): Generate dependencies respecting broken
        code markers, i.e. based on $(working-prog-subdirs) and not
        $(prog-subdirs).
