Since the .plt section and DT_PLTGOT are used by prelink to undo
prelinking for dynamic relocations, we must keep them even if there is
no PLT relocation. This patch reverted commit a3747075a.

* elf32-i386.c (elf_i386_allocate_dynrelocs): Always allocate
space for the first .plt entry.
(elf_i386_size_dynamic_sections): Always add DT_PLTGOT for .plt
section. Add DT_PLTRELSZ, DT_PLTREL and DT_JMPREL only if
there are PLT relocations.
* elf64-x86-64.c (elf_x86_64_allocate_dynrelocs): Always
allocate space for the first .plt entry.
(elf_x86_64_size_dynamic_sections): Always add DT_PLTGOT for
.plt section. Add DT_PLTRELSZ, DT_PLTREL and DT_JMPREL only if
there are PLT relocations.
