     I do not find "dotsyms" in my version of  glibc/scripts/version.awk.

      Where do I find this patch?

     I did an "ld --help" but do not see any info on "--dotsyms".
     I am using binutils-2.12.1 with the binutils-2.12.1-ppc64.patch
      applied.  What is the version of the latest binutils I should use
     for ppc64, binutil-2.13 ??

     Thanks much for your help.
