description:
make: do not evaluate the ':O' modifiers in parse-only mode

No functional change in practical usage.  Theoretically this change can
be observed by looking at the generated random numbers for the ':Ox'
modifier, but the quality or exact sequence of these random numbers is
not guaranteed anyway.
