If I am not mistaken, this has already been addressed in #5780 by making it fall back to the NEON implementation if the vector size is not 256-bit. |

Thank you for comment, I missed that correction. It looks good. I close this PR. |

This PR addresses an issue introduced in #8109.
In the previous update, GGML_NATIVE was enabled by default, which in turn enabled SVE by default. However, SVE currently only supports 256-bit operations in vec_dot, leading to errors when running on SVE 128-bit CPUs.
This fix ensures that SVE is not enabled unless GGML_SVE=ON is explicitly set at compile time.
