----------------
Unfortunately I get some failures with this. Maybe because of an unstandard
build setup.
We've started to use `-DCLANG_DEFAULT_RTLIB=compiler-rt
-DCLANG_DEFAULT_CXX_STDLIB=libc++` when building clang. And we also use
`-DLLVM_ENABLE_PER_TARGET_RUNTIME_DIR=ON`. Not sure if that is a setup that is
asking for trouble. Anyway, when running this test case we end up with
```
: 'RUN: at line 10'; /workspace/llvm/build/bin/clang -x c++ -fsyntax-only
-target powerpc64le-unknown-linux-gnu -mcpu=pwr8 -ffreestanding
-DNO_WARN_X86_INTRINSICS /workspace/clang/test/CodeGen/ppc-xmmintrin.c
-fno-discard-value-names -mllvm -disable-llvm-optzns

Not sure really how to solve that.
Maybe we should stop building like that?
Or there is a bug somewhere (such as that we only get the __config_site headers
in target specific dirs for targets that we actually build runtimes for, maybe
something that was missing in https://reviews.llvm.org/D97572)?
(Maybe @phosek could comment on that?)
Or this test case is missing some options to make it a bit more independent on
the runtimes build setup?
