Renaming mingw64 to mingw* for x86_64 architecure

[Nick Clifton <nickc@redhat.com>]

Hi DJ,

  I have applied the patch below on behalf of Kai Tietz.  This was
  part of a larger patch that allows the x86_64 mingw port to use
  either mingw32 or mingw64 as the third part of the triplet:

http://sources.redhat.com/ml/binutils/2006-12/msg00235.html

  Am I correct in assuming that your synchronisation scripts will
  bring this change into the sourceware repository, or should I apply
  the patch there as well ?

Cheers
  Nick
