交叉编译
mac m1交叉编译Linux x86_64步骤（想要gnu的话直接替换掉musl，低版本linux可能会有兼容问题）
//安装rust target
rustup target add x86_64-unknown-linux-musl
//安装linux gcc编译器
brew tap messense/macos-cross-toolchains
brew install x86_64-unknown-linux-musl
//测试+查看版本
x86_64-unknown-linux-musl-gcc -v
//添加cargo默认配置
vim .cargo/config.toml
[target.x86_64-unknown-linux-musl]
linker="x86_64-unknown-linux-musl-gcc"
//环境变量，在shell中设置或者ide中配置都行
export CC_x86_64_unknown_linux_musl=x86_64-linux-musl-gcc
//某些库可能需要其它环境变量
export CXX_x86_64_unknown_linux_musl=x86_64-linux-musl-g++
export AR_x86_64_unknown_linux_musl=x86_64-linux-musl-ar
//编译
cargo build --release --target x86_64-unknown-linux-musl
