    testsuite: outputs.exp: cleanup before running tests
    
    Use the just-added dry-run infrastructure to clean up files that may
    have been left over by interrupted runs of outputs.exp, which used to
    lead to spurious non-repeatable (self-fixing) failures.
    
    
    for  gcc/testsuite/ChangeLog
    
            * gcc.misc-tests/outputs.exp: Clean up left-overs first.
