Faulty VC++ build tools diagnostic on Windows 10

[Rojetto]

I just tried to install Rust via rustup on Windows 10 64 bit. After running rustup-init it complained about the missing VC++ build tools (as it should, I didn't have them installed).
I then downloaded and installed them with the first link it suggested (http://landinghub.visualstudio.com/visual-cpp-build-tools). After rebooting and running rustup it still complained about them allegedly missing. I then just ignored the warning and continued with the installation, which completed succesfully. The target it defaulted to and that it installed is x86_64-pc-windows-msvc. Compiling and running a simple rust program also worked, so it seems like just the diagnostic, whether the build tools are installed didn't work.

I had a similar experience and after installing rust I was able to compile the rust-sdl2 examples (after installing the required sdl2 files) so it also works on slightly more involved programs, including those relying on libraries from other languages, despite the diagnostic reporting otherwise.

Thanks for the report @Rojetto !

This is a duplicate of #660 and should be fixed in the next release.
