No, or at least not all of them are (I think they were more clearly separated 
some time ago). For example libstd, libflate, libgraphivz are runtime libs
and mini-crates useful by themself, which just happen to be shipped with 
rustc.

(in theory we'll later split a "rustc" and "rust-runtime-1.0.0" binpkgs).

Upstream binaries, for example, will install them all under /usr/local/lib/.

Indeed, it is my understanding that they should directly go in /usr/lib/* 
(at least the runtime ones). 
Otherwise, you will be forced to always compile binaries statically or with
rpaths (which is something we don't really like) and Debian will be basically 
not providing the rust runtime for dynamic binaries.

In this specific case, I think that the binary upstream provides for 
installation is what we (roughly) want to follow. I've opened another thread 
to discuss that in details, as some of the reasoning behind current packaging 
is not completely clear to me.
