If this looks ok, could someone with commit access commit this for me? Thanks.


    [GOLD] Fix _GLOBAL_OFFSET_TABLE_ value for large GOTs

    Gold resolves GOT-relative relocs relative to the GOT base +
0x8000 when the GOT
    is larger than 0x8000. However, previously the
_GLOBAL_OFFSET_TABLE_ symbol was
    set to GOT base + 0x8000 when the .got.plt was larger than 0x8000.
This patch
    makes both checks use the size of the .got section so that they
agree when to
    add 0x8000.


    * aarch64.cc (do_finalize_sections): Use size of .got section for
     the _GLOBAL_OFFSET_TABLE_ symbol computation.
