binutils/binutils: fixup version strings

Recently, all binutils versions have been renamed after a GPL compliance
issue was found and fixed in binutils;
  http://sourceware.org/ml/binutils/2011-08/msg00198.html

Although legacy symlinks have been put in place, we should now use
the new, real version strings.
