This adds just enough stubs to make the kernel compile on x86_64. Obviously it won't do anything useful - in fact it won't even attempt to boot because Multiboot doesn't support ELF64 binaries - but it gets those compiler errors out of the way so more progress can be made getting all the missing functionality in place.
