[PATCH v3 0/1] Template system

[claudius.heine.ext@siemens.com]

From: Claudius Heine <ch@denx.de>

Hi,

so after having access to the ilbers ci I could find some issues with
this patch.

I will try to describe the issue I think happened here:

Initially I added the 'do_transform_template' task with a 'before
do_build' that normally just triggers the template generation process if
the default task 'do_build' is run. The 'do_transform_template' task has
the default '${DISTRO}-${DISTRO_ARCH}' stamp-extra-info that we have to
add to pretty much all new tasks in isar.

That might be ok for normal recipes, but the buildchroot-* recipes add
stuff to the virtual default `do_build` and that now depend on the
`do_transform_template` task and its dependencies.

Currently that is a bit to complex for me to exactly figure out how
those errors get triggered, but since that works in the internal CI, but
not on ilbers, that messes up the bitbake task order.

So my solution is to remove the 'before do_build', now
'do_transform_template' is no longer executed per default. 'dpkg-base'
and the image classes add their own dependencies if they need that task.

Currently the build a ilbers ci still fails, because apparently
gettext-base is not installed there. I added gettext-base as a
dependency to the user_manual.md

regards,
Claudius
