[Bug] Segmentation fault when importing `torchmetrics` after creating a TVM CUDA target (LLVM initialization / COFF OptTable)

### Summary

Creating a TVM `cuda` target and then importing an unrelated Python package (`torchmetrics`) causes an immediate segmentation fault. There is no model compilation or runtime execution involved—simply constructing a target triggers the problem.

The crash occurs inside LLVM initialization, specifically in COFF directive parser global constructors (e.g., `llvm::opt::OptTable::buildPrefixChars()` and `_GLOBAL__sub_I_COFFDirectiveParser.cpp`), during dynamic library loading (`dlopen`).

The behavior suggests a dynamic linking / multiple-LLVM interaction.

### Minimal Reproduction

```python
#!/usr/bin/env python3
# -*- coding: utf-8 -*-

import tvm
from tvm import target
from torchmetrics import Accuracy # segmentation fault occurs here in my environment

def main():
print("Creating CUDA target...")
tgt = target.Target("cuda -arch=sm_86")
print("Target created:", tgt)

metric = Accuracy(task="multiclass", num_classes=10)
print("Metric created:", metric)

if __name__ == "__main__":
main()
```

### Actual Behavior

On my machine, the process prints "Creating CUDA target…" and then crashes with segmentation fault during import of `torchmetrics`. The beginning of the backtrace is:

```
!!!!!!! Segfault encountered !!!!!!!
File "", in llvm::opt::OptTable::buildPrefixChars()
File "", in COFFOptTable::COFFOptTable()
File "", in _GLOBAL__sub_I_COFFDirectiveParser.cpp
File "./elf/dl-init.c", in call_init
File "./elf/dl-open.c", in dl_open_worker
...
Segmentation fault (core dumped)
```

Full trace is long but mostly `dlopen` / `dl-init` frames followed by LLVM initialization frames.

---

### Expected Behavior

Importing `torchmetrics` after TVM target construction should not crash, especially before any compilation or runtime invocation occurs. The two libraries are unrelated and no model is passed to TVM.

### Notes on Repro Properties

* The issue does **not** require PyTorch, transformers, or CUDA execution.
* The critical step is:

```
tgt = target.Target("cuda -arch=sm_86")
```

followed by importing a package that triggers its own dynamic-library / symbol loading chain.

* The failure happens even if `Accuracy` is never called.
* Removing the TVM target creation avoids the crash.

### Environment

```
OS: Linux x86_64 (glibc-based)
Python: 3.10.16 (conda-forge)
NumPy: 2.2.6
PyTorch: 2.9.0+cu128
Torchmetrics: # fill here if needed
TVM: 0.22.0
LLVM: 17.0.6 (from tvm.support.libinfo())
GIT_COMMIT_HASH: 9dbf3f22ff6f44962472f9af310fda368ca85ef2
GPU: sm_86 (Ampere)
TVM target: cuda -keys=cuda,gpu -arch=sm_86 -max_num_threads=1024 -thread_warp_size=32
CUDA toolkit: likely 12.8 (based on PyTorch +cu128 build)
```

Inizia con la riproduzione Python minima fornita, in particolare target.Target("cuda -arch=sm_86") seguito dall’importazione di torchmetrics, e acquisisci il backtrace completo di dlopen/dl-init e LLVM. Esamina l’interazione tra l’inizializzazione di LLVM 17.0.6 di TVM e la catena di librerie caricate dinamicamente nell’ambiente Linux indicato. Il lavoro è completato quando l’importazione non causa più un segfault dopo la creazione del target CUDA.
