Lack of `INSTALL` file on Python 3.8.10

Documentation

I downloaded the source code for Python 3.8.10 from the FTP server using the following command:

wget https://www.python.org/ftp/python/3.8.10/Python-3.8.10.tar.xz

However, I noticed that there was no INSTALL file to assist me with the cross-compilation setup. I was able to figure out how to complete the process by reading the configure script.

Python 3.8 currently only receives security patches. The documentation for cross-compilation options is here: https://docs.python.org/3/using/configure.html#cross-compiling-options
