Add link for component availability

I always forget the link, so probably having it up visible on rustup.rs is a good idea.

wdyt?

Anybody maintaining this repo at all?

Hi @berkus

Everyone was super-busy over December but hopefully someone will be able to get to review this change soon.

I've seen that page before and it's super-useful, but I do worry about linking a community site from the official rustup pages. How about, instead, linking to https://rust-lang-nursery.github.io/rust-toolstate/ as that links through to the page you suggest adding, but it means there's only one place to update if the third party service changes location or is adopted?

[berkus]

I'm sure this can be adopted as an official page with some official rust url for sure. Right now it's just a community-maintained script and html pages, but I'm sure we can make it official?

rust-toolstate page is very limited in comparison, so i'd rather extend it with what @mexus did. I hope @mexus doesn't mind.

FYI: There is a similar discuss.

@berkus I agree that the page by @mexus is of more use, but the rust-toolstate page is official AND already links to @mexus' work. My point being that I'd rather we linked to the official page and let it deal with when the better page's functionality is either subsumed or adopted.

Hi everyone, first of all I'm super glad to see that people find my page (tool) that useful :) And yes, I'm willing to invest my time and effort in integrating the tool itself into the official toolset (provided the Rust team is ok with that), so I'll just go and ask on IRC how do I do that.

[berkus]

@kinnison that makes sense as a first step :)

[nrc]

@berkus do you want to change this PR to link to the toolstate page, or should we close it for now?

[berkus]

I will update it to link to toolslate, gimme a couple days or so.

[berkus]

@nrc here you go!

Thanks!

When is it going to go live btw?
