If you installed dahdi tools and did not specify DAHDI_PINNED=yes on the
makefile, when you run dahdi_genconf you would get an error like the following:
# dahdi_genconf
sh: span_types: command not found
Command failed (status=32512): 'span_types dumpconfig > /etc/dahdi/span-types.conf' at ...
This change allows the generator for span-types.conf and span-assignements.conf
check for the existence of the utilities before attempting to call them.
