mbuild fails to handle a .mb file with no ADD/REPLACE/DELETE directive

[Eric Swenson]

If you have an .mb file such as the following:

pr **.mb

                    MCR10084.mb         05/27/21  1633.1 pdt Thu

Installation_directory:  >sysbuild>mcrs>MCR10084;

 Build_script:             MCR10084.mb;

 Bound_obj:                bound_probe_                      IN: sss  UPDATE;
   source_arch:            bound_probe_.2.s.archive           UPDATE;
     source:               probe_info_requests_.pl1           REPLACE            compiler: pl1 -ot;

 Info:                     probe.info                        IN: sss.info;
                             add_name:  pb.info;

Where, as you can see, the probe.info entry doesn't say whether to ADD, REPLACE, or DELETE the file, no errors are issued when the .mb file is read into mbuild. But when you attempt to run the install_ec command, you do get an error:

mbuild:  install_ec
mbuild (install_ec): Operation not supported. us_command with operation:   for Seg Info: probe.info

MCR10102 changes corrected this problem.
