Description
Hi there. I'm the project lead of Adélie Linux, and we are attempting to port Rust to our distro. We've successfully built Rust on our libre 64-bit PowerPC platform, and used that to generate cross bootstraps for our other architectures.
All of the cross bootstraps work correctly, except arm64, which won't build a native compiler. While building stage1 std artifacts, the following error is seen:
Assembling stage1 compiler (aarch64-foxkit-linux-musl)

I'm fairly new to Rust, having just bought the print edition of The Rust Programming Language (2018 ed) on Monday. Therefore, I'm afraid I won't be too much help understanding the complexities of the compiler itself. (One of our contributors is much more knowledgeable about Rust and is the one who helped us generate these toolchains.) If this is beyond the scope of the Rust project, feel free to close this issue and we won't bother you again.
