* Fix wrong suffix x86_64-linux-gnu in native python module shared library
* Python native module shared library is cross-compiled for correct
architecture but filename had an incorrect suffix 'x86_64-linux-gnu'.
As per python_cmake_module, if PYTHON_SOABI environment variable is not
defined, it'll query it from native's python sysconfig module.
https://github.com/ros2/rosidl/blob/master/python_cmake_module/cmake/Modules/FindPythonExtra.cmake
So adopt a solution similar to the one adopted below, where PYTHON_SOABI
is set explicitly for our specific build.

because of wrong value of -Wl,-rpath provided to the cross-linker.
This patch makes use of -Wl,-rpath-link option added unconditionally to all
catkin-based builds to aleviate the problem.
NB: The proper fix though should either replace -Wl,-rpath with
-Wl,-rpath-link where it's needed or use correct path to target
libs in -Wl,-rpath.

By default meta-ros uses python2. In case you want to get
python3-compatible builds add the following line to your local.conf:
ROS_USE_PYTHON3 = "yes"
