Building perf with LIBBPF_DYNAMIC (ie not the default static linking of libbpf with perf) is breaking as the libbpf isn't version 1.7 or newer, where dont_enable is added to bpf_perf_event_opts. To avoid this breakage add a compile time version check and don't declare the variable when not present.
