0. Preparation
Install cross-compiler on /opt
/opt/gcc-linaro-7.4.1-2019.02-x86_64_aarch64-linux-gnu
export PATH=/opt/gcc-linaro-7.4.1-2019.02-x86_64_aarch64-linux-gnu/bin/:$PATH
export CC=aarch64-linux-gnu-gcc

1. download glibc
http://mirrors.nju.edu.cn/gnu/libc/
download glibc-2.31.tar.gz and plugins

tar -xvf glibc-2.31.tar.gz 
tar xvf ~/下載/glibc-crypt-2.1.tar.gz 
tar xvf ~/下載/glibc-libidn-2.9.tar.gz 
tar xvf ~/下載/glibc-linuxthreads-2.5.tar.bz2 
tar xvf ~/下載/glibc-localedata-2.0.6.tar.gz 
tar xvf ~/下載/glibc-ports-2.9.tar.bz2 
tar xvf ~/下載/nss_db-2.2.tar.gz 
tar xvf ~/下載/nss_lwres-0.92.tar.gz

2. make

mkdir /opt/glibc
cd /opt/glibc
~/glibc-2.31/configure arm-linux --target=arm-linux --prefix=/opt/glibc --host=aarch64-linux-gun --enable-add-ons

if succeed, Makefile will be generated.

make
