dep.name.replace("-", "_"),

This should almost certainly be dep.library_name() or something similar, to handle dependencies which rename their library (I don't know of any example build logs to see if it's an issue though). See rust-lang/rust#76296 as well, we can't actually give a unique name here when things like duplicate renamed dependencies come into play.

Rustdoc expects the library name anyway, we can't do anything about that until rust-lang/rust#76296 is fixed. We definitely shouldn't be using .replace() though.
