[Mlir-commits] [mlir] [mlir-cpu-runner] Pass --exclude-libs to linker when building runner (PR #122329)

[Andrea Faulds]

https://github.com/andfau-amd created https://github.com/llvm/llvm-project/pull/122329

This fixes a conflict between the version of LLVM linked against by the runner and the unrelated version of LLVM that may be dynamically loaded by a graphics driver. (Relevant to #73457: fixes loading certain Vulkan drivers.)
