rust musl toolchain

Rust musl toolchain, used to compile rust-musl release binaries.

Motivation

• Produce statically-linked binaries for x86_64 and armv7 Linux
• Use musl as the standard C library
• Use libc++ as the standard C++ library
• Leverage clang and lld to enable cross-language link-time optimization

Usage

In order to build your project for a given target, run

docker run -w"$PWD" -v"$PWD":"$PWD" -t manifoldfinance/rust-toolchain:1.60.0-armv7-unknown-linux-musl cargo build

Alternative, just create a shell alias

alias cargo-armv7='docker run -w"$PWD" -v"$PWD":"$PWD" -t manifoldfinance/rust-toolchain:1.60.0-armv7-unknown-linux-musl cargo'

In order to be able to run cargo-armv7 build, cargo-armv7 test, etc.

Note
the tests should work too, although they are compiled for the target platform, with help of user-mode QEMU installed inside the toolchain image.
