    PR28391, strip/objcopy --preserve-dates *.a: cannot set time

    After commit 985e0264516 copy_archive function began to pass invalid
    values to the utimensat(2) function when it tries to preserve
    timestamps in ar archives.  This happens because the bfd_stat_arch_elt
    implementation for ar archives fills only the st_mtim.tv_sec part of
    the st_mtim timespec structure, but leaves the st_mtim.tv_nsec part
    and the whole st_atim timespec untouched leaving them uninitialized

            PR 28391
            * ar.c (extract_file): Clear buf for preserve_dates.
            * objcopy.c (copy_archive): Likewise.
