Trying to install 1.8.0 on freebsd succeeds without actually installing the toolchain

[jyn514]

Steps

1. Beg, borrow, or steal a FreeBSD machine
2. Install rustup.
3. rustup install 1.8.0

info: sync channel updates ...
info: latest update on 2016-04-12, rust version 1.8.0 ...

  1.8.0-x86_64-unknown-freedbsd unchanged - (toolchain not installed)

Possible Solution(s)

Rustup should either install the toolchain or give an error that it's not available.

Notes

Output of rustup --version: 1.22.1
Output of rustup show: omitted because I can't get copy/paste to work in my VM.

So freebsd is present in the channel though the rustc and cargo components are not available for that target in there. What's odd is that ought to fail to install

I can confirm this is replicatable on Linux:

dsilvers@listless:~/dev-git/rustup$ rustup install 1.8.0-x86_64-unknown-freebsd
warning: toolchain '1.8.0-x86_64-unknown-freebsd' may not be able to run on this system.
warning: If you meant to build software to target that platform, perhaps try `rustup target add x86_64-unknown-freebsd` instead?
info: syncing channel updates for '1.8.0-x86_64-unknown-freebsd'
info: latest update on 2016-04-12, rust version 1.8.0 (db2939409 2016-04-11)

  1.8.0-x86_64-unknown-freebsd unchanged - (toolchain not installed)

info: checking for self-updates
dsilvers@listless:~/dev-git/rustup$

I'll look into it

Actually this appears to just be a case of crappy error message. It didn't create a toolchain entry with no components, it just failed to install the toolchain and then exited zero which is somewhat confusing for scripts
