svn commit: r327858 - head/share/mk

New Revision: 327858

Log:
  Add a hack to disable AUTO_OBJ for 'old style' kernel builds.
  
  Another solution would be to extend the Makefile.sys.inc idea, or a .no_obj
  file, to more places but I would rather keep that limited to the top-level
  build for now to not impact performance (statting a file in every make call)
  or to bring unintended side-effects.
