Add padding to the plt section so that its size is a multiple of its
entry size.
* elf32-tilepro.c (allocate_dynrelocs): Use PLT_ENTRY_SIZE as size
of header.
(tilepro_plt_entry_build): Account for new header size.
(tilepro_elf_finish_dynamic_sections): Ditto.
(tilepro_elf_plt_sym_val): Ditto.
* elfxx-tilegx.c (allocate_dynrelocs): Use PLT_ENTRY_SIZE as size
of header + tail.
(tilegx_elf_finish_dynamic_sections): Account for new padding.
