Archlinux ARM image

[ericwoud]

Because I need a switchdev device for testing code that is also used by switchdev devices, I bought the Olimex AM3359 board.

I needed it to run the latest linux kernel, so I created an archlinux package for it.

I haven't tidied up the build script, so I only release the image:

https://github.com/ericwoud/buildAMarch

The linux kernel package can be build on a x86-64 host running archlinux (in a chroot).

This image comes with a patched version for testing my patches, so for a clean kernel, you can build a clean version.

Change:
```
_gitroot="https://github.com/ericwoud/linux.git"
_gitbranch="bpir-nftflow-net-next"

```
