SDL2: unexpected hash

[jcelerier]

Original issue: emscripten-ports/SDL2#120

The problem is still happening here with recent emscripten versions :/

If you are updating the port, please update the hash.

I tried downloading https://github.com/libsdl-org/SDL/archive/4b8d69a41687e5f6f4b05f7fd9804dd9fcac0347.zip with wget / curl and it gives me:

(the .zip is indeed the SDL source)

Does this still happen now? This has been a flaky problem in the past, and I don't see any errors on our CI, so hopefully the server side fixed it by now.
