In addition to the malformed diagnostic, the tracking issue has been closed already. According to https://rust-lang.github.io/rfcs/1721-crt-static.html#lazy-link-attributes, this is supposed to be a permanently-unstable implementation detail. In that case, should the link be updated to point somewhere else?

The wording can be easily fixed at
rust/src/librustc_metadata/native_libs.rs
Line 165 in 699f83f
The link can't be changed to a non-issue because of how the machinery is currently set up, but we can update the description of the ticket to point at RFC 1721.
