    gcc47: Add __stack_chk_fail_local hack from gcc44
    
    Like gcc44 before it, gcc47 is complaining about the hidden symbol of
    __stack_chk_fail_local.  This patch swildner added to gcc44 will fix the
    issue, but it is a bit of a hack.  A true fix may end up touching libc,
    rtld, and other bits.  The original code is supposd to conserve a PIC
    register.
    
    Note that vendor-built GCCs on FreeBSD exhibit the same behavior and as
    a consequence only the patched base compiler can be used to build certain
    ports.
    
    This hack should be fixed properly as soon as convenient.
