Proposed patch

Hi Martin,

  Please could you try out this patch and let me know what you think.

  The patch makes two changes.  Firstly it adds a new configure time
  option --enable-f-for-ifunc-symbols, which if used makes nm display
  f for local ifuncs and F for global ifuncs.  By default however this
  feature is not enabled.

  The second change is to add a new command line option to nm 
  --ifunc-chars=CHARS.  If used then nm with display CHARS[0] for global
  ifunc symbols and CHARS[1] for local ifunc symbols.  (The local symbol
  can be left unspecified, in which case 'i' will be used).

Cheers
  Nick
