  Log:
  Normally, when a header file is removed from the build (as i4b headers
  were recently), a simple 'make cleandepend; make depend' is sufficient
  to keep the tree buildable after a cvs update when doing incremental
  builds.
  
  However, kdump and truss use a script which searches for header files
  that define ioctls, and generates C code that includes them.  This
  script will usually not need updating when a header file is removed,
  so the normal dependency mechanism will not realize that it needs to
  be re-run.  One is therefore left with code that references dead files
  but will only be removed by a full 'make clean', which defeats the
  purpose of incremental builds.
  
  To work around this, modify the cleandepend target in bsd.dep.mk to
  also remove any files listed in a new variable named CLEANDEPFILES,
  and modify kdump's and truss's Makefiles accordingly.
