----------------
Hi, adding this module path overwrites the `llvm_check_linker_flag` from `llvm/cmake/modules/LLVMCheckLinkerFlag.cmake` with the one defined in `cmake/Modules/CheckLinkerFlag.cmake`, which does not check the linker but the compiler.
This breaks our gcc+ld build because ld does not support `--color-diagnostics`.

Our downstream issue is here: https://github.com/GPUOpen-Drivers/llpc/issues/1645
