    Remove reference to Solaris 9 in comment of add_options_for_tls
    
    Since r5-172-gd9f069ab4f6450, the code no longer matches the
    comment as the code for Solaris 9 support was removed.
    This just updates the comment to reference AIX only as
    the code does.
    
    Committed as obvious.
    
    gcc/testsuite/ChangeLog:
    
            * lib/target-supports.exp (add_options_for_tls): Remove
            reference to Solaris 9 in comments.
