Linker error on Windows with lld-link: relocation against symbol in discarded section

it actually ends up crashing lld-link, but the errors come first, so I think it's also doing something wrong.

I tried with and without `used_linker` and get the same thing either way, whereas `used_linker` fixed lld on other platforms.

The `GTESTS` here is the distributed_slice, in the `rust_gtest_interop` crate.

This should be reproducible on Windows outside of Chromium with `--target=x86_64-pc-windows-msvc -Clinker=clang-cl -Clink-arg=-fuse-ld=lld`.
