    arch/x86: Link walkcbfs.S instead on including it in bootblock.S
    
    The code flow doesn't fall through to walkcbfs, as it does in the rest
    of bootblock.S. Instead, walkcbfs is called (albeit via a jmp). The
    linker cannot know this when walkcbfs.S is included directly.
    
    When we use a CAR bootblock, we lose several hundred bytes because
    walkcbfs is not garbage-collected, yet it isn't used. This problem
    is solved by assembling walkcbfs.S separately, and linking it.
