[ros-release] solving new platform/architecture release problems

Hi Vincent,

We're working on solutions for both of those + collada-dom.

We have the ability to blacklist packages in the build files on the farm.
For anything that is related to a specific distro that's the right place to
do it. For example these packages are blacklisted for arm in Indigo:

There is a level of granularity that we could consider extending to support
blacklisting a specific target/arch pair inside of the build file if we
want to keep a specific arch running but not put it into it's own build

The one time it might be appropriate to tag something in the package.xml is
if the package has binary code included inside which is not compiled but
supplied as a blob. However as we strongly discourage those cases and have
very few of them, I think that continuing to use the blacklists for them is


PS colladadom and couchdb should be fixed shortly. Some targets are already
deployed. (Thanks to Jose for help backporting.) We're still working on
openni on ARM. We have versions compiling from source so it shouldn't be
too long.
