The patch makes sure that catkin does not find the package.xml in the rtt_roscomm_pkg_template folder for any reason, neither in the package source nor in devel-space nor in install-space.
This is required if the devel-space is located within the source folder, which in general is possible. Otherwise the template is found as package (with a broken package.xml) when cmake is executed the 2nd time after the template has been copied to devel-space.
