Errors when running release.py

[dionescu]

I've been running into some problems running release.py.

First of all, the docker image could not find the sources. I noticed that there is no call to download.sh from the scripts called by release.py. Even if I download the sources in advance, built_grte will delete them. Additionally, assuming one fixes this problem, the path TAR_DIR=readlink -f ${TAR:-/sources} appears to be wrong since the sources are located at lrte/grte/sources.

Second, what base docker image is this intended for? If I use ubuntu, with "python release.py --docker_image=ubuntu" I get errors about make and gcc not being installed yet.

Thanks!
