Update build instructions

## Building
First, we need to check out the source and rebuild the Rust runtime using a
bare-metal target and no floating point support:
bare-metal target and no hardware floating point support:
# Get our source code.
git clone
cd toyos-rs
multirust override nightly-2015-11-08
# Set up a Rust compiler.
curl -sSf | sh
rustup update nightly-2016-09-16
rustup override set nightly-2016-09-16
# Get a copy of the Rust source code so we can rebuild core
# for a bare-metal target.
git submodule update --init
make runtime
Our copy of Rust has been patched to incoporate a version of the
`libcore_nofp.patch` from [rust-barebones-kernel][], and the `rust`
submodule points at a source tree that has been tested with the specific
`nightly` build mentioned above.
From here, we should be able to build a kernel and run it using QEMU:
make run
You should be able to type.
