I think this should be core-$(CONFIG_ARCH_RV64I) to get the same result.
Or even better just core-y given that the Kconfig dependencies should
ensure you can't ever enable CONFIG_BPF_JIT for 32-bit builds.

I don't think this comment adds any value. In fact it is highly
confusing given that we use bpf for a lot more than networking these
days.

Please don't just add stubs files. This patch should probably be merged
into the one adding the actual implementation.
