skip relinking checks for webassembly

[DerThorsten]

When building a shared library / a python package with c extension for emscripten-wasm32 one is facing this

 × error Error building package: unknown platform for relinking
Error:   × unknown platform for relinking

Atm this PR:

• skip relinking for wasm
• skip linking checks for wasm

This is not done very elegant atm and might even be wrong, but I believe for the boa/conda-build based workflow, we also just skip anything which involves parsing the *.so files.

With that, the build of the regex python package builds successful. Still working on integrating the testing.

This works! I can run the pyjs_code_runner in the tests to test the package wasm package!

The test section is somewhat complicated for emscripten-wasm32, but it works!

tests:
  - script: python -m pip install playwright && playwright install && pyjs_code_runner run script browser-worker --conda-env $PREFIX --mount  $(pwd):/tests --script /tests/test_regex.py  --headless
    requirements:
      build:
        - pyjs_code_runner
        - pip
      run:
       - pyjs
       - pytest
      
    files:
      recipe:
        - test_regex.py

caviat: for macos I have to install playwright via pip as it is not available for conda-forge on mac

Nice! I think multi line scripts should work fine, too, btw

indeed. Looks better

tests:
  - script: python -m pip install playwright && 
            playwright install && 
            pyjs_code_runner run script browser-main 
              --conda-env $PREFIX 
              --mount  $(pwd):/tests 
              --script /tests/test_regex.py  
              --headless
      
    requirements:
      build:
        - pyjs_code_runner
        - pip
      run:
       - pyjs
       - pytest
      
    files:
      recipe:
        - test_regex.py

Also the output looks very nice =)

You can also use : | for the YAML block syntax or you can use a list of commands (as a YAML list) :)

[wolfv]

Then you shouldn't need the &&
