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.
