    powerpc: fix release image building for Apple partitions
    
    awk changed somewhere between 14 and 15 and it stopped accepting
    a hexadecimal number as its input - it will always return 0.
    This results in a very badly written apple boot block.
    
    So just remove it; do the math in shell.
