* bootcard.c: Eliminate pointers to API configuration tables in the
	main configuration table. Reference the main configuration table and
	the API configuration tables directly using the confdefs.h version
	rather than obtaining a pointer to it. This eliminated some
	variables, a potential fatal error, some unnecessary default
	configuration structures. Overall, about a 4.5% reduction in the code
	size for minimum and hello on the SPARC.
