PATCH: Don't add addend for R_X86_64_GLOB_DAT/R_X86_64_JUMP_SLOT

[H.J. Lu]

Hi,

x86-64 psABI specifies that R_X86_64_GLOB_DAT and R_X86_64_JUMP_SLOT
should use the symbol value without addend.  This patch removes addend
from R_X86_64_GLOB_DAT/R_X86_64_JUMP_SLOT.  It wasn't a problem before
since addend is cleared for R_X86_64_GLOB_DAT and R_X86_64_JUMP_SLOT:

do_glob_dat:
          bfd_put_64 (output_bfd, (bfd_vma) 0,
                      htab->elf.sgot->contents + h->got.offset);
          rela.r_info = htab->r_info (h->dynindx, R_X86_64_GLOB_DAT);
          rela.r_addend = 0; 

        {
          rela.r_info = htab->r_info (h->dynindx, R_X86_64_JUMP_SLOT);
          rela.r_addend = 0;
          plt_index = htab->next_jump_slot_index++;
        }

Tested on x86-64.  OK for 2.18?
