Wishlist: Link parity with `lld` instead of `ld`

[niklasad1]

The benchmarks of linking with ldd instead of ld looks interesting (see rust-lang/rust#50584),

Now, ldd is shipped on nightly but is not stabilized yet rust-lang/rust#39915 (comment)

However, if you have clang and ldd installed you can test it by:

export RUSTFLAGS="-Clinker=clang -Clink-arg=-fuse-ld=lld" 
time cargo build

Is there anything we can do here? I believe we won't be using lld until it is shipped with rust stable. And if it will be, according to the comment, it will be turned on by default. So I believe, we can close the issue, as it is totally not up to us when it's done
