After the release of ROS groovy, there is no strong reason to
continue to work on the cross-compilation of the previous ROS
version fuerte. Hence, this commit removes the initial
non-functioning recipe and the reference in the README file.

For cross-compiling ROS fuerte, the repository at
https://github.com/yida/yida-collections


might be a better starting point anyway.
