Expected behavior

Using electron/universal configured with osxUniversal in forge config, we expect all dependent modules will receive the correct arch and build themselves accordingly.

Actual behavior

We are using ffmpeg-static in our Electron app, but when the universal build is created, only the arm64 ffmpeg binary exists. I have confirmed that the ffmpeg-static module can be rebuilt in CLI with an arch param (npm rebuild --arch=x64 -f ffmpeg-static and confirmed with file node_modules/ffmpeg-static/ffmpeg). In this case the correct binary is build/fetched. But when running the universal build with forge, only os.arch() seems to be respected, which in this case is an M1 machine.

It seems electron-forge isn't passing the correct arch to dependencies. If there were hooks in the universal build process, or some env vars set, I could manually rebuild this one ffmpeg module according to an arch. For example ffmpeg-static does obey process.env.npm_config_arch, so if I were able to set that in between the x64 and arm64 builds (or electron/universal did), the module would build the correct ffmpeg binary.

I have attempted using hooks in electron-forge to try and switch based on arch, but that value is always universal. Also, building the app on separate Intel and M1 machines does produce the appropriate ffmpeg binary.

Steps to reproduce

Set up a project with electron-forge and ffmpeg-static, then attempt a universal Mac build.
