fix: optional arch parameter

[breautek]

Platforms affected

Android

Motivation and Context

Building bundles broke at some point between 9.0.0 and nightly.

Fixes #1151

Description

When building bundles, the arch setting is not supplied. This is provided through an options parameter, but you cannot deconstruct a object that doesn't exists. Therefore, I made the options parameter default to {}. The arch option remains optional.

Testing

Ran npm test.
