Zero-sized binaries in ~/.cargo/bin (ChromeOS?)

The latest version of rust (1.36.0 as of this comment) is not working. After installation on an i686 ChromeOS system, I get all zero byte binaries in ~/.cargo/bin. By the way, I fully agree with @josephRice. I see so many projects like this that require the user's path to be modified. I don't understand why this is so popular but it's the WRONG WAY to install an application. See below:

chronos@localhost /usr/local/tmp $ curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
info: downloading installer

Welcome to Rust!

This will download and install the official compiler for the Rust programming 
language, and its package manager, Cargo.

It will add the cargo, rustc, rustup and other commands to Cargo's bin 
directory, located at:

  /home/chronos/user/.cargo/bin

This path will then be added to your PATH environment variable by modifying the
profile files located at:

  /home/chronos/user/.profile
  /home/chronos/user/.bash_profile

You can uninstall at any time with rustup self uninstall and these changes will
be reverted.

Current installation options:

   default host triple: i686-unknown-linux-gnu
     default toolchain: stable
  modify PATH variable: yes

1) Proceed with installation (default)
2) Customize installation
3) Cancel installation

Rust is installed now. Great!

To get started you need Cargo's bin directory ($HOME/.cargo/bin) in your PATH 
environment variable. Next time you log in this will be done automatically.

To configure your current shell run source $HOME/.cargo/env
chronos@localhost ~ $ source $HOME/.cargo/env
chronos@localhost ~ $ cd .cargo/bin/
chronos@localhost ~/.cargo/bin $ ls -la

Also, why does the script download everything twice? Sorry for the rant.

Reproduce the reported rustup installation on an i686 ChromeOS system, starting with the installer command and the resulting files in ~/.cargo/bin. Compare component installation with the reported output and verify whether rustc can report its version. Done means the installed binaries are non-empty and the default toolchain works.
