 Description   

When python34 and python34-devel is installed in CentOS 7 the API fails to compile. It has the following errors:

/home/linuxjedi/Programming/Git/mariadb-columnstore-api/python/pymcsapi_wrap.cxx: In function ‘PyTypeObject* SwigPyObject_TypeOnce()’:
 
/home/linuxjedi/Programming/Git/mariadb-columnstore-api/python/pymcsapi_wrap.cxx:1968:5: error: missing initializer for member ‘_typeobject::tp_finalize’ [-Werror=missing-field-initializers]

cmake -DCMAKE_BUILD_TYPE=Debug .
make -j4

Will require a new version of Swig which we may well need for other connectors later down the line. Since this is only an issue for debug builds we can wait.

We needed to update to Swig 3.0.12 on CentOS due to MCOL-1612.

This change will solve this error as well.

For QA:
confirm that CentOS can build the debug version of the api.

Verified, added a note in the Readme.md to uninstall os version of swig on centos7 first otherwise cmake tries to use the os version and fails the version check.
