[RFC PATCH 2/7] Rust: module build infrastructure

Make the grub build infrastructure able to detect a Rust toolchain on a supported platform and build modules partially written in Rust. In order to use this you will need: - to be building for x86_64-emu (more platforms added later) - to have a nightly rust toolchain: rustup toolchain ins

[RFC PATCH 4/7] Rust: add the rust_hello module

Build an actual module with Rust! This module, built whenever COND_RUST is enabled, does the following: - Prints a message when the module is loaded. - Registers a command which prints hello when run. - Deregisters the command when the module is unloaded. You can build it with the usual mak
