To build for RISC-V you only need binutils + gcc (riscv64). The errors you get when running `newt test ...` are because the tests run on a simulated environment. You need gcc-multilib and a 32-bit libc-dev. Not sure which distro you use, but installing `libc6-dev`on a 64-bit distr installs only the 64-bit libc. To get 32-bit, for Ubuntu you would need to install like this: `apt-get install linux-libc-dev:i386 `. Or just search with your package manager for something like "libc-dev-i386".
