The current verifier error message states that tail_calls are not allowed in non-JITed programs with BPF-to-BPF calls. While this is accurate, it is not the only scenario where this restriction applies. Some architectures do not support this feature combination even when programs are JITed. This update improves the error message to better reflect these limitations.
