+       * elf32-i386.c (elf_i386_check_relocs): Pass FALSE for non
+       PC-relative PLT to NEED_DYNAMIC_RELOCATION_P.
+       * elf64-x86-64.c (elf_x86_64_check_relocs): Create PLT for
+       R_X86_64_PC32 reloc against dynamic function in data section.
+       Pass TRUE for PC-relative PLT to NEED_DYNAMIC_RELOCATION_P.
+       (elf_x86_64_relocate_section): Use PLT for R_X86_64_PC32 reloc
+       against dynamic function in data section.
+       * elfxx-x86.c (elf_x86_allocate_dynrelocs): Use PLT in PIE as
+       function address only if pcrel_plt is true.
+       (_bfd_x86_elf_link_hash_table_create): Set pcrel_plt.
+       * elfxx-x86.h (NEED_DYNAMIC_RELOCATION_P): Add PCREL_PLT for
+       PC-relative PLT.  If PLT is PC-relative, don't generate dynamic
+       PC-relative relocation against a function definition in data
+       secton in PIE.  Remove the obsolete comments.
+       (elf_x86_link_hash_table): Add pcrel_plt.
