    multilib_global: Fix KERNEL_VERSION expansion problems
    
    KERNEL_VERSION gets expanded at runtime to contain the real kernel
    version. There is code to ensure the signatures are determinisic but
    the multilib expansion code breaks this.
    
    Exclude the variable from the datastore used for expansion to avoid this.
