macOS v6.0.2 prebuilt binary for `arm64` Node v14 is actually `x86_64`

[stepankuzmin]

It seems like the gl-v6.0.2-node-v83-darwin-arm64.tar.gz prebuilt binary is the same as gl-v6.0.2-node-v83-darwin-x64.tar.gz

$ node -p "process.arch"
arm64

$ git clone --branch v6.0.2 https://github.com/stackgl/headless-gl.git
$ cd headless-gl
$ rm -rf ~/.npm/_prebuilds/
$ npx prebuild-install --verbose --debug

Both libs have the same cputype 16777223 / 0x1000007, which is the identifier for x86_64 https://developer.apple.com/documentation/foundation/1495005-mach-o_architecture/nsbundleexecutablearchitecturex86_64

Yes, it looks like the darwin-arm64 binary is the same as the darwin-x64 one. Curious how that could happen, as it was part of an automated build.

Thanks for flagging this. I've removed the prebuilt binary in the meantime, and will look into re-uploading a new one, possibly for a new build in the near future.

Are you able to build from source OK?

Yep, I'm building from the source atm. Thanks!
