    hurd: rule out some mach headers when generating errno.h
    
    While mach/kern_return.h happens to pull mach/machine/kern_return.h,
    mach/machine/boolean.h, and mach/machine/vm_types.h (and realpath-ing them
    exposes the machine-specific machine symlink content), those headers do not
    actually define anything machine-specific for the content of errno.h.
    
    So we can just rule out these machine-specific from the dependency
    comment.
