Now I think about this further, we're only depending on do_build in order
to ensure that we get all the dependencies included in the source release
via the recrdeps task. If there were a better way to do that then perhaps
rm_work wouldn't cause any problems, and we also wouldn't waste time
building stuff that we aren't going to use.

I've tried:

 ALL_DEPENDENCIES = "${RDEPENDS} ${DEPENDS}"
 do_source_release[depends] = "${@' '.join([s+':do_source_release ' for s in d.getVar('ALL_DEPENDENCIES', True).split()])}"

in the bbclass (which is still inherited by all recipes) and then just
running the source_release task on the final images.

Unfortunately this fails when IMAGE_INSTALL contains package names that are
generated using PACKAGES_DYNAMIC such as gstreamer plugins. :(

ERROR: Nothing PROVIDES 'gstreamer1.0-plugins-good-audioparsers'. Close matches:
  gstreamer1.0-plugins-good
  gstreamer1.0-plugins-base
  gstreamer1.0-plugins-bad
  gstreamer1.0-plugins-good RPROVIDES gstreamer1.0-plugins-good-audioparsers

Is there a correct way to get a task to run for every recipe that is
required by an image?

Thanks.

Mike.
