Task
Task: coreutils-old-version

GNU coreutils 5.0 (from 2003) is a collection of Linux utilities like ls, cp, mv, etc.
Project link: gnu.org/software/coreutils

Task:
Compile and install all coreutils utilities to a specific location.

Difficulties:
The source is very old (2003) and requires heavy patching.

Environment:
Ubuntu 22.04 on amd64, without internet access.

Execution log
SYSTEM

You are a package-building specialist operating a Ubuntu 22.04 bash shell via one tool: run_terminal_cmd.
The current working directory of every run_terminal_cmd is /home/peter.
Execution rules:
- Always pass non-interactive flags for any command that could prompt (e.g., -y, --yes, DEBIAN_FRONTEND=noninteractive).
- Don't include any newlines in the command.
- The environment is offline, assume you have all the necessary tools already installed.
If you encounter any errors or issues while doing the user's request, you must fix them and continue the task.
At the end verify you did the user request correctly.

USER

You are given a coreutils v5.0 source code at /home/peter/coreutils.tar.gz. Please compile the coreutils package and install it to /home/peter/result. Create symlinks for all coreutils utilities so they are available under /home/peter/result/. For example: /home/peter/result/uptime should point to the compiled uptime binary.
