The way things were intended to work, sim_info would always be run
and each target would have sim_info print the things the user
told it to print.  If the user didn't tell the simulator to print
anything, then sim_info would print nothing.  Up until your patch,
it has always worked this way.  ie. your sim_info is supposed to
check various flags and print what the user told it to print.
