From: Nick Desaulniers <ndesaulniers@xxxxxxxxxx> Subject: compiler-clang: remove version check for BPF Tracing bpftrace parses the kernel headers and uses Clang under the hood. Remove the version check when __BPF_TRACING__ is defined (as bpftrace does) so that this tool can continue to parse kernel headers, even with older clang sources.
