[FEATURE REQUEST] ASan for dynamic linking

I've tried compiling something with `emcc src/main.c -s MAIN_MODULE=1 -lwebsocket.js --js-library my_js_lib.js -s EXPORTED_RUNTIME_METHODS=['allocateUTF8'] -fsanitize=address -s ALLOW_MEMORY_GROWTH -gsource-map --source-map-base http://127.0.0.1:4000/build -o build/my_build.js`

... but got:
```
emcc: error: ASan does not support dynamic linking
```

Is there any way ASan support for dynamic linking could be added?

Thanks!
