README.md

I made a minimal Rust demo.

This needs a rebuild of the core library with xargo (https://github.com/japaric/xargo) for working soft floating-point support.

Steps:

$ rustup default nightly

$ rustup target add powerpc64le-unknown-linux-gnu

$ rustup component add rust-src

$ cargo install xargo

$ make
$ make run

ln -sf hello_world.bin main_ram.bin
../core_tb > /dev/null
