Raspberry pie update tool chain

In other environments Compilation of bin file , It doesn't work on my raspberry pie , It turned out to be due to glibc The library of is too old , So I can only upgrade raspberry pie glibc 了 .

Check the raspberry pie libc Version of ：

strings /lib/aarch64-linux-gnu/libc.so.6 |grep GLIBC_

Upgrade steps ：

1. get 2.34 glibc from internet
    wget http://ftp.gnu.org/gnu/glibc/glibc-2.34.tar.gz
2. tar -zxvf glibc-2.34.tar.gz
3. cd glibc-2.34
4. mkdir build
5. cd build
6. sudo apt-get install bison   (if you haven't never install bison, bison --version to look version )
6. ../configure --prefix=/opt/glibc-2.34
7. sudo make install
8. Delete libc.so.6 Then it may cause the system command to be unavailable , The following methods can be used to solve :
LD_PRELOAD=/opt/glibc-2.29/lib/libc-2.29.so  ln -s /opt/glibc-2.29/lib/libc-2.29.so /lib/aarch64-linux-gnu/libc.so.6
If the above update fails, you can use the following command to restore :
LD_PRELOAD=/lib/aarch64-linux-gnu/libc-2.31.so ln -s /lib/aarch64-linux-gnu/libc-2.31.so /lib/aarch64-linux-gnu/libc.so.6    // libc-2.31.so This item is the version before the system upgrade

stay configure and make Stage , It will take a long time , Later, it was unbearable , Upgrade the operating system , Upgrade to 22.04 edition ,glibc It's relatively new , Then run programs compiled in other environments , Run as expected OK.
