CMake Error at /data/buildroot/buildroot-test/instance-0/output/host/arm-buildroot-linux-gnueabi/sysroot/usr/lib/cmake/llvm/CheckCompilerVersion.cmake:40 (message):
  Host GCC version should be at least 5.1 because LLVM will soon use new C++
  features which your toolchain version doesn't support.  Your version is
  4.8.3.  You can temporarily opt out using
  LLVM_TEMPORARILY_ALLOW_OLD_TOOLCHAIN, but very soon your toolchain won't be
  supported.
