        libiberty/
        * simple-object-common.h (struct simple_object_functions):
        Change copy_lto_debug_sections callback signature.
        * simple-object-elf.c (SHN_HIRESERVE, SHT_SYMTAB_SHNDX,
        SHF_INFO_LINK): Add defines.
        (simple_object_elf_copy_lto_debug_sections): Instead of
        leaving not to be copied sections empty unnamed SHT_NULL
        remove them from the target section headers and adjust section
        reference everywhere.  Handle SHN_XINDEX in the symbol table
        processing properly.
        * simple-object.c (handle_lto_debug_sections): Change
        interface to return a modified string and handle renaming
        of relocation sections.
