llama.cpp b9601 fixes Vulkan build with eMesaHoneykrisp patch

llama.cpp, the widely-used C/C++ library for running large language models locally, has released tag b9601 to address a specific build regression. The release fixes a Vulkan compilation issue on Linux by adding an ifdef for eMesaHoneykrisp, a Mesa driver codename that was causing the build to fail. The problem originated from commit #24306 and was breaking continuous integration pipelines. The patch ensures that the Vulkan backend can be compiled cleanly, which is critical for users leveraging AMD GPUs or other Vulkan-compatible hardware for local LLM inference.

This is a maintenance release that does not add new features, but it ensures stability across the extensive build matrix supported by llama.cpp. The release includes builds for macOS (both Apple Silicon and Intel, plus iOS XCFramework), Linux (x64, arm64, s390x with CPU, Vulkan, ROCm 7.2, OpenVINO, SYCL FP32), Android (arm64 CPU), and Windows (x64 and arm64 CPU, CUDA 12/13, Vulkan, SYCL, HIP). Several configurations are disabled (e.g., macOS KleidiAI, Windows SYCL, openEuler). For developers and researchers who rely on llama.cpp for self-hosted LLMs, this quick fix keeps the toolchain reliable and buildable without workarounds.
