make building "map" files optional dependent upon configuration options
Most of the "map" files are long since no longer used by modern distributions,
so this patch aims to address that by making their creation optional (we will
eventually kill off most of these for good). For now, make_map_files defaults
to being set but you can explicitly set it in your depmod.conf file:
make_map_files no
make_map_files yes
There is also a command line option "-m" which can be used to force.
