Python tests for dynamic build

[vidyalakshmir]

Update 4/14/26
PR 191 has a clean version of python build script. Hence closing this.

This PR is to aimed to track the progress of the python tests for dynamic build of python and fix failed tests. We will have another PR to actually integrate python tests to the repo. Preferably a single test script that works for both static and dynamic builds.

We use

• dylink_impl_integration_Mar5 branch of lind-wasm repo. This repo currently have some hacks since multi-process and signal support is not supported in dynamic loading. Glibc fixes from PR is integrated into the dylink_impl_integration_Mar5 branch
• build-python branch of lind-wasm-apps repo

How to run the tests:

cd lind-wasm
git pull
git checkout dylink_impl_integration_Mar5
make
scripts/make_shared_glibc.sh
scripts/make_shared_libm.sh 
cd src/lind-boot
cargo build --features disable_signals
cd ~/
git clone --recursive https://github.com/Lind-Project/lind-wasm-apps.git
cd lind-wasm-apps/
make merge-sysroot
git checkout build-python
cd python
./build_python_wasm.sh
./build_shared_python_wasm.sh
./run_python_shared_tests.sh
