Comment:
Please add `make_check_target=check`, `checkdepends="python3-ply"` and gtest, testsuite submodules so tests can be run. Use d2163dace09d647bccf34b9b82a6f05a3b23cf29 version of testsuite, matching release.

On moving submodules, use commit hashes rather than globbing:
```
rmdir third_party/wasm-c-api
mv ../wasm-c-api-${_wasm_c_api_commit} third_party/wasm-c-api
```
