Hi Martin,

  Thanks.

  Now the question is what letter should we use for global ifunc symbols ?

  I see three options:

   1. Use 'I' for global ifunc symbols and another character (eg '>') for
      indirect symbols.

   2. Leave 'I' as it is (ie indicating an indirect symbol) and use
      another character (eg 'F') for global ifuncs.

   3. Leave 'I' as it is and use another pair of characters (eg 'f' and 'F')
      for ifuncs symbols.

  Do you have any preference ?

  We also have the issue of backwards compatibility.  There are probably
  tools out there the rely upon the current characters returned by nm, so
  this behaviour will have to be controlled by a command line option.

  Perhaps something like: --global-ifunc-char=<character>


Cheers
  Nick
