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