rk3568创建基于Ubuntu18.04交叉编译遇到的坑

尽管配置过rk3288，觉得rk3568也不会有啥问题，但还是掉坑了。
一、安装依赖库
安装完ubuntu后，先进行升级

sudo apt update
sudo apt upgrade

然后安装依赖库

$ sudo apt-get install repo git-core gitk git-gui gcc-arm-linux-gnueabihf u-boot-tools 
$ sudo apt-get install device-tree-compiler gcc-aarch64-linux-gnu mtools parted 
$sudo apt-get install libudev-dev libusb-1.0-0-dev python-linaro-image-tools 
$ sudo apt-get install linaro-image-tools autoconf autotools-dev libsigsegv2 m4 
$ sudo apt-get install intltool libdrm-dev curl sed make binutils build-essential gcc 
$ sudo apt-get install g++ bash patch gzip bzip2 perl tar cpio python unzip rsync flex 
$ sudo apt-get install bc wget libncurses5 libqt4-dev libglib2.0-dev libgtk2.0-dev 
$ sudo apt-get install libglade2-dev cvs git mercurial rsync openssh-client subversion 
$ sudo apt-get install asciidoc w3m dblatex graphviz python-matplotlib libc6:i386 
$ sudo apt-get install libssl-dev texinfo genext2fs
$ sudo apt-get install lib32stdc++6
$ sudo apt-get install g++-arm-linux-gnueabihf
$sudo apt-get install gcc-arm-linux-gnueabihf
$ sudo apt-get install g++-aarch64-linux-</
