Description:

Compiling C to WASM with emcc (as seen here https://developer.mozilla.org/en-US/docs/WebAssembly/C_to_wasm) fails with output:

```
emcc wasm_test1.c -s WASM=1 -o hello.html
shared:INFO: EM_IGNORE_SANITY set, ignoring sanity checks
Unknown option '--minimize-wasm-changes'
emcc: error: '/usr/bin/wasm-emscripten-finalize --detect-features --global-base=1024 --minimize-wasm-changes /tmp/emscripten_temp_c2clk_7t/hello.wasm -o /tmp/emscripten_temp_c2clk_7t/hello.wasm.o.wasm' failed (1)
```
The '--minize-wasm-changes' option was added to wasm-emscripten-finalize 6 days ago:

https://github.com/WebAssembly/binaryen/commit/b43807a835fc878e5eefcb8b4a18aff62d7f4540

after latest binaryen release, v96 (11 days ago).

In emscripten/emscripten.py, this was added to the args for the call to wasm-emscripten-finalize 5 days ago, and it looks like that has been merged in:

https://github.com/emscripten-core/emscripten/commit/ed2e2dc60ba2213cba7ad96cee18ff0fba75bf66

Additional info:
* package version(s)
emscripten 2.0.1-1

Steps to reproduce:

1) install latest emscripten package
2) compile C with `emcc <filename>.c -s WASM=1 -o <filename>.html
