    [ARM] 4074/1: Flat loader stack alignment
    The ARM EABI requires doubleword (8-byte) stack alignment at all public 
    points.  The patch below makes the bFLT loader honour this.
    It's always safe to start with a doubleword aligned stack so it doesn't seem
    worth making this conditional on CONFIG_AEABI.
