Subject: [PATCH 50/54] perf build: Force llvm/clang test compile output to .make.output

From: Jiri Olsa <jolsa@...nel.org>

So we can see the output of feature compile in following files:

  tools/build/feature/test-llvm.make.output
  tools/build/feature/test-llvm-version.make.output
  tools/build/feature/test-clang.make.output
