    Properly handle note sections and segments

    When dumping notes, get note alignment from either note section or note
    segment.  To support notes generated by assemblers with

    https://sourceware.org/bugzilla/show_bug.cgi?id=22492

    we treate alignment as 4 bytes if it is less than 4.  Otherwise, we skip
    notes if alignment isn't 4 nor 8 bytes.

    We should call load_separate_debug_file only if e_shstrndx != SHN_UNDEF.

        * readelf.c (process_notes_at): Add an argument for note
        alignment.  If note alignment is less than 4, use 4 byte
        alignment.  Otherwise, skip notes if alignment isn't 4 nor
        8 bytes.
        (process_corefile_note_segments): Pass segment alignment to
        process_notes_at.
        (process_note_sections): Pass section alignment to
        process_notes_at.
        (process_object): Call load_separate_debug_file only if
        e_shstrndx != SHN_UNDEF.
