ia64/ld/bfd pltoff problem

[Belochapka, Konstantin]

Ia64 ld crashes when it meets instruction that contains @pltoff

I have discovered that the crash happens inside of the 
ia64_size_dynamic_sections() function, file \bfd\elfxx-ia64.c
It appears that on the function entry pltoff section info was not yet created. 

I have made fix for this problem

function
elfNN_ia64_check_relocs, file \bfd\elfxx-ia64.c
....
line 2480:
      if (need_entry & NEED_PLTOFF) {
        dyn_i->want_pltoff = 1;
        if( !get_pltoff (abfd, info, ia64_info)) return FALSE;   /* create 
pltoff info */
      }                 


Hope someone more familiar with the source will make this fix in more elegant 
way.
