Update buildroot to 2024.02.3 LTS release

* Update to release 2024.02.3
* Update build env to SLE 15.6
* Drop ppc64 and s390x since we are no longer producing K3s for these
  platforms. We'll leave riscv64 since it may be coming at some point in
  the future.

 ## Upgrading to new buildroot version
 
-To upgrade to a new buildroot version, you must follow 4 steps:
-
-1 - Modify the BUILDROOT_VERSION in scripts/download
-
-2 - Check what is the busybox version in the new buildroot package. Then, upgrade the package/busybox.config by cloning the [busybox project](https://github.com/mirror/busybox) and then:
-```
-git checkout $busybox_version
-cp $K3S_ROOT_PATH/package/busybox.config .config
-make oldconfig
-# Choose the new options
-cp .config $K3S_ROOT_PATH/package/busybox.config
-```
-3 - Follow the same steps with the buildroot/ configurations. The command `make oldconfig` also works in the buildroot project
-
-4 - Verify if the upgrade worked correctly by comparing the old tarball and the new one. If the same files are there, then you are set
+To upgrade to a new buildroot version:
+
+1. Check out a new branch for your work: `git checkout -B bump-buildroot origin/master`
+1. Modify the `BUILDROOT_VERSION` in scripts/download
+2. Run `make download` to prepare a Docker image for further work 
+4. For each target architecture: 
+ 1. Start a shell in the resulting image: `docker run --rm -it -e BUILDARCH=<ARCH> k3s-root:bump_buildroot /bin/bash`
+ 2. Run `./scripts/download && ./scripts/patch`
+ 3. Run `cd /usr/src/buildroot && make olddefconfig`
+ 4. Outside the container, split changes to the buildroot `.config` into `buildroot/config` and `buildroot/<ARCH>config`
+ 5. Run `make BUILDARCH=<ARCH>`
+ 6. Verify if the upgrade worked correctly by comparing the old tarball and the new one. If the same files are there, then you are set.
+ If the build failed, or some files are missing, you may need to remove or adapt patches or config for the new buildroot version.
