I'm seeing build failures with this change, while using runtimes build:

and similar.

Configured via:

```

```

The file's present, so I guess it's a missing include directory:

```
# find /var/tmp/portage/llvm-runtimes/openmp-22.0.0.9999/work/runtimes_build-.arm64 -name omp-tools.h
/var/tmp/portage/llvm-runtimes/openmp-22.0.0.9999/work/runtimes_build-.arm64/openmp/runtime/src/omp-tools.h
```
