Describe the bug

Test fails only on Windows (in CI). Most likely due to wildcard character * in the name of object file.

Failed here: #19272 (https://github.com/intel/llvm/actions/runs/16147484488/job/45632837493)

[steffenlarsen]

This seems to be a problem in the clang-linker-wrapper producing invalid filenames. It can be reproduced with a simple SYCL program simple.cpp:

#include <sycl/sycl.hpp>

int main() {
    sycl::queue Q;
    Q.single_task([](){});
    return 0;
}

compiled with

clang++  -fsycl --offload-new-driver -fsycl-targets=spir64_gen -Xsycl-target-backend=spir64_gen "-device *" simple.cpp
