description:
make(1): allow the inconsistency with Lst_OpenS to be discovered

The -dL option is intended to find bugs in Makefiles and in make itself,
therefore enabling the consistency check is ok there.  Having this check
available by default increases the chances of the bug being found and
finally fixed.
