      3 #	Configuration variables (default values are below):
      4 #
      5 #	S	must be set to the top of the 'sys' tree.
      6 #	KERNDST	may be set to the location of the directory where library
      7 #		objects are to be built.  Defaults to ${.OBJDIR}/lib/kern.
      8 #	KERN_AS	may be set to 'obj' to build a object from the library's
      9 #		object files.  (Otherwise, a library will be built.)
     10 #		Defaults to 'library'.
     11 #	KERNMISCCPPFLAGS
     12 #		Miscellaneous cpp flags to be passed to the library's Makefile
     13 #		when building.
     14 #	KERNMISCMAKEFLAGS
     15 #		Miscellaneous flags to be passed to the library's Makefile when
     16 #		building.  See library's Makefile for more details about
     17 #		supported flags and their default values.
