Task
Task: jq-static-musl

jq 1.8.1 is a command-line JSON utility for viewing and transforming JSON.
Project link: github.com/jqlang/jq

Task:
Compile and install statically-linked jq to a specific location. The binary must use musl C library (not the standard glibc).

Difficulties:
musl toolchain setup, avoiding glibc-only assumptions.

Environment:
Ubuntu 22.04 on amd64, with 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.
- You can use sudo.
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 jq v1.8.1 source code at /home/peter/jq.tar.gz. Please compile the jq package using musl as the C standard library and install it to /home/peter/result. Create a symlink from /home/peter/result/jq to the compiled jq binary. The binary must be statically linked and must use musl (not glibc).

Libraries have been installed in:
   /home/peter/result/lib

If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the '-LLIBDIR'
flag during linking and do at least one of the following:
   - add LIBDIR to the 'LD_LIBRARY_PATH' environment variable
     during execution
   - add LIBDIR to the 'LD_RUN_PATH' environment variable
     during linking
   - use the '-Wl,-rpath -Wl,LIBDIR' linker flag
   - have your system administrator add LIBDIR to '/etc/ld.so.conf'

See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.
