    rules.make: Explicitly sequentialize steps in the bootstrap process
    
    In case of parallel builds, sub-make invocations inherit the
    parallelization settings of the caller make.  That might lead to the
    execution of, for example, confclean and chicken-boot-stage1 in
    parallel, which breaks builds.
    
    Improve that by explicitly sequentializing the steps that cannot be
    executed in parallel.
