Linux arm 64 support

[johnzuk]

Is there any plan to introduce support for the linux arm64 platform?

Hello @johnzuk,

Normally building for Linux amr64 is possible.
Did you encounter a problem?

We plan to build the nightly for ARM64, the corresponding issue is #326

Sorry I wasn't precise in the description. I tried to build docker the image but it is very tightly bound to the X86_64 architect.
There is ARG https://github.com/lightpanda-io/browser/blob/main/Dockerfile#L6 but x86_64 value is hardcoded in several places.
Also there is no prebuild linux arm64 binary there: https://github.com/lightpanda-io/zig-v8-fork so this line will fail:
https://github.com/lightpanda-io/browser/blob/main/Dockerfile#L63
So i tried first to build image in zig-v8-fork repo but its also bond to x86_64

So as a working solution i combined build both repositories in one dockerfile like so:

yes, this is the main blocker to have a fast docker build for linux arm.
Unfortunatly, AFAIK Github doesn't provide natively linux ARM instances.

see #326

I just noticed GH offers arm64 support for linux now 😓
I'm trying to update the builds. first with v8.
