Cannot install current version of llama-cpp-python 0.3.16 on Windows (backend independent)

# Prerequisites

Please answer the following questions for yourself before submitting an issue.

- [x] I am running the latest code (`Version 0.3.16`).
- [x] I carefully followed the [README.md](https://github.com/abetlen/llama-cpp-python/blob/main/README.md).
- [x] I [searched using keywords relevant to my issue](https://docs.github.com/en/issues/tracking-your-work-with-issues/filtering-and-searching-issues-and-pull-requests) to make sure that I am creating a new issue that is not already open (or closed).
- [x] I reviewed the [Discussions](https://github.com/abetlen/llama-cpp-python/discussions), and have a new bug or useful enhancement to share.

# Expected Behavior

When installing `llama-cpp-python` with the respective environment variables mentioned in the docs set, the installation of the dependency should succeed.

# Current Behavior

The installation failed. See the error log below.

# Environment and Context

Environment variables:

- `CMAKE_GENERATOR=MinGW Makefiles`
- `CMAKE_ARGS=-DGGML_OPENBLAS=on -DGGML_BLAS=ON -DGGML_BLAS_VENDOR=OpenBLAS -DGGML_OPENBLAS=on -DCMAKE_C_COMPILER=E:/Development/w64devkit/bin/gcc.exe -DCMAKE_CXX_COMPILER=E:/Development/w64devkit/bin/g++.exe`

I also tried this with Vulkan and ROCm backend and got exactly the same error.

System and dependency information:

* AMD Ryzen 7 7800X3D
* AMD 7900 XTX
* Operating System: `Windows`
* Python version: `3.13.6`
* w64devkit version: `2.4.0`
* make version: `GNU Make 4.4.1
Built for x86_64-w64-mingw32`
* g++ version: `g++.exe (GCC) 15.2.0`

# Failure Information (for bugs)

The installation failed (see error log below). The error stays the same no matter what backend (OpenBLAS, Vulkan, ROCm) is chosen

# Steps to Reproduce

1. Set the environment variables as mentioned above
2. Install the dependency via `pip` or any other package manager (I use `uv sync`)
3. See the failing error message
