commit 43a8475ca01b676fb764aaed0c4ed1cc16fc3c87

    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.
