reintroduce getallmavencoordinates

[ebarboni]

Removed this target as I though it was no more used but it allow to shorten the external artefacts

[neilcsmith-net]

btw. I assume this should be targetted at delivery?

[mbien]

yes, this has to be delivery, otherwise rc2 jenkins build will have those exceptions too:

Changed the base branch. Looks OK to me. @ebarboni please double check and merge.
