Support LLVM lld as the linker

[ghost]

Currently lld is not supported as the Rust linker on some platforms because Vector is unable to parse configs when linked using it, see discussions for #791 and #732. The reason is that the version of typetag used by Vector has rust-ctor crate as a dependency which uses some features specific to GNU ld and doesn't work with lld.

As mentioned in discussion for #946, recently the problem was reported to be solved in the upstream. We need to update the dependency and ensure that Vector works with it.
