Thank you for the effort. I was talking to some wasi folks in Berlin

I have near 0 experience with autotools. I had no plans to touch that portion. Let me know what needs to be done there. The example files were removed from this repo and placed at https://github.com/yurydelendik/sassc/tree/wasi/wasm |

I suggest rebasing on master because a large changeset was just merged |
It is the changes I made to make compilation work for clang with "wasm32-wasi" target and the wasi-sdk.

I'm on vacation until next week. I'll take a look when I'm back.
