OpenModelica pull request 17175 against wasm-jit

1 libraries of the baseline run were not tested by the pull request run: Buildings_11.

The baseline is the newest run of wasm-jit, not the commit the pull request is based on, so a difference can also come from something merged into wasm-jit since the pull request was branched.
