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:

  /root/.cargo/bin

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

  /root/.profile

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

Current installation options:

   default host triple: powerpc64-unknown-linux-gnu
     default toolchain: stable
  modify PATH variable: yes

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

    This looks like it might be cargo. I downloaded a binary beta of cargo
    https://static.rust-lang.org/dist/2018-10-30/cargo-beta-powerpc64-unknown-linux-gnu.tar.gz and got the same Illegal Instruction.

    https://static.rust-lang.org/dist/2018-10-30/rustc-beta-powerpc64-unknown-linux-gnu.tar.gz seemed to work well enough to print it's version where cargo doesn't.

    Looks like there is a cargo bug on this rust-lang/cargo#6320

    Turns out I think this really is a rustup issue. Lots of information in rust-lang/cargo#6320.
    Rustup 1.0.0 is the only version that seems to work on powerpc64. OpenSSL sends SIGILL (illegal instruction) signals by design for CPU feature detection and so rustup has to account for that and continue.

    Is this any better now, given that we are no longer using OpenSSL for TLS by default?

    Probalby fixed by rust-lang/rust#58986 and rustup release after that.

    Edit: mobile's spellcheck used wrong language.

    @mati865 Thanks for the rapid followup! I guess we can close it then :)
