Actually this is an update for the last two weeks, as there was no update last week.

Things that happened last two weeks:

* The build pipelines in the manifests dropped a bunch of packages that are not used by the images, such as filesystem support for xfs/squashfs and cdrom support. This makes the build smaller and faster and requires less packages to be supported.

* There is a new makefile target extension "*.ext4" which creates an image similar to the normal one but without a multi-partition setup. This is useful on some boards where the boot happens in a non traditional way and all that is needed is the root filesystem.

* There is a new makefile target "*.tar" which makes it easy to generate a tarballs containing the contents of what would otherwise be in image.

* The makefiles now support passing strings with spaces in them in the DEFINES variable by escaping them with a backslash.

* The two images "kernel_dev" and "osbuilder" were combined into a single "developer" image that has the content of the previous as well as some container tooling.
