        (NEW_PLT_HEADER_SIZE, NEW_PLT_ENTRY_SIZE): New.
        (PLT_HEADER_SIZE, PLT_ENTRY_SIZE): Conditionalize on secureplt.
        (ALPHA_ELF_LINK_HASH_PLT_LOC): Remove.
        (struct alpha_elf_link_hash_entry): Add plt_offset.

        (elf64_alpha_calc_got_offsets_for_symbol): Don't report internal
        error as user error.
        (elf64_alpha_size_plt_section_1): Allocate one plt entry per
        got subsection.
        (elf64_alpha_size_plt_section): Size .got.plt section.
