+ * Use this option to configure mono to run on WebAssembly. It will
+ set both host and target to the WebAssembly triplet. This overrides
+ the values passed to `--host` or `--target` and ignored what config.sub guesses.

+ This is a workaround to enable usage of old automake versions that don't
+ recognize the wasm triplet.
