[Buildroot] [Patch v7 02/10] rust-bin: new package

Eric Le Bihan eric.le.bihan.dev at free.fr
Sun Jul 23 08:11:58 UTC 2017 

This package provides a pre-built version of rustc, the compiler for the
Rust programming language, fetched from the upstream project.

A pre-built version of the standard library for the host as well as one
for the chosen target are also fetched and installed.

Only the host variant is provided to allow the user to cross-compile
Rust programs and run them on the target.

The menuconfig entry for rustc is also updated to expose this provider.
