Arch and OS not detected on RPi 3 with Ubuntu MATE

[Phyllostachys]

I went to www.rustup.rs to see if it would work on my RPi 3 but it reported that it couldn't detect the OS.

Upon some more investigation, it seems that rustup.sh does properly detect armv7l and Linux, it just doesn't have a source for rustc, rustc-docs, and cargo:

error: some components unavailable for download: 'rustc', 'rust-docs', 'cargo'
rustup: command failed: /tmp/tmp.k3xO6b3Vc4/rustup-init

Perhaps I jumped the gun on submitting this issue. I went ahead and made a fork, adding the support, but I don't think it is time yet to expose it.

I'm guessing that this compiler just wasn't published in the 1.8 stable build and this will work if you continue to install nightly with rustup default nightly.

Handling toolchain install failure more gracefully would help make this more clear.

Added the pull request. Since it sounds like it is technically supported I figured that it wouldn't hurt.

Since it is all merged in, closing the issue.
