[Pkg-rust-maintainers] Bug#955208: Bug#955208: rustc: rustup is not available on Debian

[Matt Corallo]

What is the use-case for rustup being packaged? rustup is just a thin wrapper around downloading binaries from a third 
party, so why not just download it from the same third-party? It is geared at installing things in the local users' home 
directory anyway.

Packaging rustup doesn't address the many limitations of rustup's rustc vs Debian's (excellently-packaged) rustc (eg 
cross-language LTO, LLVM plugins, etc).
