Do you prefer to have builtin enum? If we do this, we will emit this enum all the time,
regardless of whether people uses this builtin or not. Are you worried about API
stability?

I think defining explicitly in libbpf/btf.h probably a better choice? 
Defining commonly used macros like __bpf__ or __BPF__
makes more sense. Hidden enum's seems really rare.
