Thanks!

I don't have knowledge for Bazel build system, but it surprised me a bit that
the build system doesn't use the makefiles in Perf.

I think it is the right way to fix makefiles in Perf for cross building with
LLVM/Clang. I would like hold on the Android document updating - once the
building is fixed, we will have better knowledge for building perf on Android.

Thanks,
Leo
