    lto/96385 - avoid unused global UNDEFs in debug objects

    Unused global UNDEFs can have side-effects in some circumstances so
    the following patch avoids them by treating them the same as other
    to be discarded DEFs - make them local.

            * simple-object-elf.c
            (simple_object_elf_copy_lto_debug_sections): Localize global
            UNDEFs and reuse the prevailing name.
