    ld: Rewrite lang_size_relro_segment_1

    1. Compute the desired PT_GNU_RELRO segment base and find the maximum
    section alignment of sections starting from the PT_GNU_RELRO segment.
    2. Find the first preceding load section.
    3. Don't add the 1-page gap between the first preceding load section and
    the relro segment if the maximum page size >= the maximum section
    alignment.  Align the PT_GNU_RELRO segment first.  Subtract the maximum
    page size if therer is still a 1-page gap.
