`rustc -Z ls libfoo.rlib` doesn't show extern linked libraries

[lilyball]

rustc -Z ls doesn't show any extern dynamic libraries in an rlib. These dynamic library dependencies are propagated downstream, so it has to be recorded in the rlib crate metadata, so rustc -Z ls should display it.

Triage:

$ rustc -Z ls libfoo.rlib

So I think this is fixed?

Closing. It seems that this is fixed, and it's not clear what needs to be done here if it isn't; please reopen with expected output if this isn't actually fixed.
