* Parallelize kernel source compression
This surpringly saves a lot of time:
M1: from 340 to 90 seconds
Intel: from 527 to 222 seconds (2 cores 4 threads)

* Add buildx target
buildx can use remote builders and automatically generate the multiarch manifest.
A properly configured builder is required :
First create docker context for the remote builders :
$ docker context create node-<arch> --docker "host=ssh://<user>@<host>"
Then create a buildx configuration using the remote builders:
$ docker buildx create --name kernel_builder --platform linux/amd64
$ docker buildx create --name kernel_builder --node node-arm64 --platform linux/arm64 --append
$ docker buildx use kernel_builder
$ docker buildx ls

* Do not tag use the architecture suffix for images built with buildx

* Add make kconfigx to upgrade configs using buildx
To update configuration for 5.10 kernels use :
make -C kernel KERNEL_VERSIONS=5.10.104 kconfigx
