They aren't NOPs, they're just unimplemented. Do we actually need them here? I'm not sure which relocation sections kldxref is processing.

True. Meanwhile I just put them here for the purpose of not letting the existing tool failing due to some obviously in-use stuff like ifunc/irelative/jmpslot. All the other values are those our krtld doesn't recognize anyway so they should be errored out in this case. Implementing them would be good as well for better multi-klds symbols resolving.

I think a better way to handle this is to add an abort() or so to these cases, then run "make universe -DMAKE_JUST_KERNELS" and see if anything fails.
