I've made a comment on the test "I think we should use llvm-objdump -d -r to check relocations."
If you do that, `-NEXT` is sufficient to ensure that there is no `R_RISCV_RELAX` :)

With my experience on https://github.com/llvm/llvm-project/pull/79099 , I think two `R_RISCV_RELAX` are sufficient. I probably need to follow up on the spec.
