Hi Guys,

  I am applying this patch on behalf of a user who tried to use
  readelf's --unwind option on an AArch64 binary, but found that it was
  not supported.  Eventually I hope to add support for that
  architecture, but in the meantime this extra documentation might help
  other users.

Cheers
  Nick
