    Enable 64-bit archives in ar and ranlib

    Since existing ld and gold support the 64-bit (MIPS) ELF archives, we
    can use the 64-bit (MIPS) ELF archives as 64-bit archives.  Since the
    plugin target is used to create archive in plugin-enabled ar, we need
    a way to enable 64-bit archives in the plugin target.  This patch adds
    --enable-64-bit-archive to bfd to force 64-bit archives in ar and
    ranlib.  Since both 64-bit MIPS and s390 ELF targets currently use
    64-bit archives, 64-bit archives are enabled by default for them.
    64-bit archive is generated automatically if the archive is too big.

    Tested on Linux/x86 and Linux/x86-64 with existing ld and gold.
