Log:
  Use .MAKE.LEVEL being defined as a bootstrap aid when providing
  fallback targets to build the aic generated files. fmake doesn't like
  the current construct, and since it doesn't have .MAKE.LEVEL, just
  don't provide the fallback targets for fmake. This gives a little
  extra compatibility to old systems trying to build new kernels at
  almost no cost to the current code.
