Setting up multi build

[Taknok]

Multi arch build with docker buildx would allow to run all griffin+ on mips or arm arch.

Hi @Taknok, thank you for the hint. I'll have a look at it soon. Is there any use case you need it for?

Running it on a new mac or a raspberry for exemple.
I did several tries with github action as I do not have an azurepipeline. You can take a look here : https://github.com/Taknok/docker-strongswan

As github action does only provide x64 arch I had to take the buildx method, but I am not familiar enouth with azurepipeline and it may provides various arch and one pipeline by arch can be done.

The buildx relies on qemu and currently there is an issue with qemu. When running on a x64 and emulating an x32, the issue prevents to build cryptography with rust. This issue will probably never be fixed as it would require to track full x32 inode to map x64 inode (qemu currently return x64 inode and the x32 does not appreciate).
Core issue : https://gitlab.com/qemu-project/qemu/-/issues/263
Rust tracking : rust-lang/cargo#8719

So I drop arm32 in my tests.

Interesting documentation:

Sorry for miss click.
