最后make 得到output/host 这个就包含gcc 和 sysroot的目录
将host mv 到 /opt/host-arm64-armhf下
sudo ln -s /opt/host-arm64-armhf//opt/host-arm64-armhf/arm-buildroot-linux-gnueabihf/sysroot/lib/ld-linux-armhf.so.3 /lib/ld-linux-armhf.so.3
创建/etc/ld.so.conf.d/armhf.conf 文件
文件添加
/opt/host-arm64-armhf//opt/host-arm64-armhf/arm-buildroot-linux-gnueabihf/sysroot/lib
sudo ldconfig

make -j4
sudo make install
重启服务
sudo systemctl restart systemd-binfmt.service
已同样的方式编译i686-gcc，设置运行库 ~/.bashrc 添加Path
export PATH=/opt/host-arm64-i686/bin:$PATH
export PATH=/opt/host-arm64-armhf/bin:$PATH
export PATH=/opt/host-arm64-x86_64/bin:$PATH
