* 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.
