    RS6000/BFD: Remove dead duplicate `config.bfd' target matchers
    
    Remove duplicate `rs6000-*-aix5.[01]' and `rs6000-*-aix[5-9]*' target
    configuration selectors meant to correspond to `powerpc64-*-aix5.[01]'
    and `powerpc64-*-aix[5-9]*' respectively for the purpose of BFD target
    vector selection in `config.bfd'.
    
    These selectors were added with commit 9a9e2ca33263 ("rs6000 xcoff bfd
    config"), <https://sourceware.org/ml/binutils/2010-12/msg00372.html>,
    and have been dead right from the beginning, because they appear twice
    each in the case statement, which means the earlier instance of each
    takes precedence and the other one is ignored.  Here ones that alias to
    `powerpc-*-aix5.[01]' and `powerpc-*-aix[5-9]*' respectively immediately
    above are used instead.

    	* config.bfd <rs6000-*-aix5.[01], rs6000-*-aix[5-9]*>: Remove
    	duplicate `case' selectors.
