By default, pahole makes use only of BTF features introduced with kernel v5.2. Features that are added later need to be turned on with explicit feature flags, such as --btf_gen_floats. According to [1], this will hinder the people who generate BTF for kernels externally (e.g. for old kernels to support BPF CO-RE). Introduce --btf_gen_all that allows using all BTF features supported by pahole.
