Hi Tristan,

When I tried this I found some build errors for my all-64 target 
(configured with --enable-64bit-bfd --enable-targets=all):

   bfd/elfnn-ia64.c: In function 'elfNN_ia64_info_to_howto':
   bfd/elfnn-ia64.c:215:5: error: implicit declaration of function 
'ELFNN_R_TYPE'
   bfd/elfnn-ia64.c: At top level:
   bfd/elfnn-ia64.c:278:1: error: no previous prototype for 
'bfd_elfNN_ia64_after_parse'

And so on.  Please could you check this locally and assuming that it 
happens for you too, fix it ?

Cheers
   Nick
