Build Failure When Enabling KleidiAI on ARMv9 in llama-cpp-python ≥ 3.10.0

When I try to install the latest version of **llama-cpp-python** and enable **KleidiAI** on an **ARMv9 CPU**, I use the following command:

```bash
CMAKE_ARGS="-DGGML_NATIVE=OFF -DGGML_CPU_ARM_ARCH=armv9-a+i8mm+dotprod -DGGML_CPU_KLEIDIAI=ON" pip3 install llama-cpp-python
```

However, during the wheel-building process, it fails with the following error:

```bash

These CMake flags (`-DGGML_NATIVE=OFF -DGGML_CPU_ARM_ARCH=armv9-a+i8mm+dotprod -DGGML_CPU_KLEIDIAI=ON`) have already been tested on **llama.cpp**, and the build succeeds there.

The installation works for **llama-cpp-python==3.9.0**, but starting from **3.10.0**, the build fails with the error above.
