rust: Force all dependencies to be linked, used or not
`rustc` added an unstable feature that makes `--extern` do what we
originally wanted - it links the provided library, *even* if the source
code does not reference it.
The primary use case for this is that it makes it possible for us to
build dylibs out of `#![no_std]` crates without modifying the source,
because we can pass in `--extern force:path/to/libstd.dylib.so`.
