This commit updating LLVM from 20.x to 21.x broke the build of bpftrace:

  https://autobuild.buildroot.net/results/2bf/2bf26b4848796ab031ab0767b97aba63a35f1184/build-end.log

CMake Error at CMakeLists.txt:168 (message):
  Unsupported LLVM version found via
  /home/autobuild/autobuild/instance-14/output-1/host/aarch64-buildroot-linux-gnu/sysroot/usr/include:
  21


CMake Error at CMakeLists.txt:169 (message):
  Only versions between 16 and 20 are supported

Qais, Bernd, could one of you have a look?

Thanks!

Thomas
