Hmm.  In testsuite/lib/prune.exp there's

    # Ignore stabs obsoletion warnings
    regsub -all "(^|\n)\[^\n\]*\[Ww\]arning: STABS debugging
information is obsolete and not supported anymore\[^\n\]*" $text ""
text

maybe you can (selectively for pdp11) add similar pruning of the
'target system does not support debug output' message?
I think you should be able to use

   if { [istarget pdp11-*-*] } then {
     regsub -all " ... " ...
   }
