git riscv-gnu-toolchain

$ git clone https://gitee.com/mirrors/riscv-gnu-toolchain

进入源码目录：

$ cd riscv-gnu-toolchain

注意上面 clone 的主仓库并不包含子仓库的内容，所以需要继续更新子仓库。注意这里首先排除了 qemu 这个子仓库，一来因为 qemu 完整下载太大；二来 qemu 对 toolchain 的编译本身来说其实并不需要。

$ git rm qemu
$ git submodule update --init --recursive

耐心等待子仓库下载完成。
