Investigate occasional error with catkin-native and the recipes

[bulwahn]

My conjecture is that once I installed catkin in the build environment,
any recipe that uses catkin-native breaks down, because it uses the catkin files in the "staging dir" instead of those in the "staging dir native".

It can be mitigated by starting with a clean build environment, and avoid installing catkin.

How could we tweak the recipes to avoid picking up those catkin files in the staging directory at all?

The error is:

The error did not reappear in the last few weeks, so it probably does not occur anymore.
