Remove "setdefs.h" and arrange to generate it automatically at ELF kernel build time. "gensetdefs.c" is a utility which scans a set of ELF object files and outputs a line ``DEFINE_SET(name, length);'' for each linker set that it finds. When generating an ELF kernel, this is run just before the final link to generate "setdefs.h". Remove the init_sets() function from "setdef0.c", and its call from "machdep.c". Since "gensetdefs.c" calculates the length of each set, it is no longer necessary in an ELF kernel to count the set elements at kernel initialization time. Also remove "set_of_sets" which was used for this purpose. Link "setdef0" and "setdef1" into the kernel only if building for ELF. Since init_sets() is no longer used, there is no need to link them into an a.out kernel.
