    Adjust LOAD segment to generate GNU_RELRO segment

    This patch fixes 2 GNU_RELRO segment bugs:

    1. lang_size_sections didn't properly align base to the maximum
    alignment power of sections between DATA_SEGMENT_ALIGN and
    DATA_SEGMENT_RELRO_END.
    2. ld failed to adjust LOAD segment to generate GNU_RELRO segment
    when LOAD segment doesn't fit GNU_RELRO segment.  This is

    https://sourceware.org/bugzilla/show_bug.cgi?id=14207

    We "fixed" ld by not generating GNU_RELRO segment.  This patch
    adjusts LOAD segment to generate GNU_RELRO segment.  It fixes
    PR ld/16322 and at the same time it also fixes PR binutils/16323
    since now we can adjust LOAD segment if it is too small.

        doesn't fit PT_GNU_RELRO segment, adjust its p_filesz and p_memsz.
