Commit: Fix resource leaks reported by cppcheck

[Nick Clifton]

Hi Guys,

  After running cppcheck:
  
    http://sourceforge.net/apps/mediawiki/cppcheck/index.php?title=Main_Page

  over the binutils sources I found a few more resource leaks.  So I am
  checking in the attached patch to fix them. 

Cheers
  Nick
