I assume that easywasm.wasm is built using emscirten's SIDE_MODULE or MAIN_MODULE commands?

The format of the dylink section using in emscripten (the output of wasm-ld -shared and wasm-ld -pie) changed to add list of needed dyligs to the dylink section. I imagine that easywasm.wasm was built with a slightly older version of emscripten or llvm? Can you confirm that? Can you try re-building with a newer version? Technically we should just ignore errors like this since dylink is a custom section....

BTW if you using emscripten's SIDE_MODULE to try to build a portable wasm file you probably want to switch to using the STANDALONE_WASM option which was designed for this purpose.
