Workaround for windows-gnu rust-lld test failure

The test run-make/amdgpu-kd has an issue on windows-gnu where rust-lld will sometimes fail with error 0xc0000374 (`STATUS_HEAP_CORRUPTION`).

This works around the issue by passing `--threads=1` to the linker as suggested [here](rust-lang/rust#115985 (comment)). Note I don't know if this will help and it happens only sometimes in our CI so it's hard to test.
