Log:
  Fix .depend.foo.o tracking for sys/conf/files defined compilations.
  
  Some example files:
    ia32_genassym.o
    acpi_wakecode.o
  
  The old mkdep method also lacked tracking these files.
  
  Objects defined in sys/conf/files with no-obj and no-implicit-rule get their
  own targets defined in the kernel Makefile but lack having their objects added
  to DEPENDOBJS so never get a .depend file generated.  Normally if an object is
  in OBJS it will get a .depend file.
  
  Fix this by looking for .o files in CLEAN and ensuring they are part of
  the -MD filtering and .depend loading.  This is a hack.  Other solutions
  could exist involving sys/conf/files or config(8) to auto add these to
  DEPENDFILES/DEPENDOBJS but this method seems reliable enough without being
  intrusive or error-prone for new files.
