[PATCH] RS6000/BFD: Remove dead duplicate `config.bfd' target matchers

["Maciej W. Rozycki" <macro at linux-mips dot org>]

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.

Hi Alan,

 I've spotted this by chance while looking into the XFAIL list for the 
SEGMENT_START test case and it looks to me like a plain oversight.  If 
there's something that I missed, then I'll be happy to get enlightened.

 Otherwise, OK to apply?

  Maciej
