    toolchain: gdb: Add optional python support
    
    Compile gdb with python support optionally.
    
    To use the Python support in gdb some extra python files are needed,
    install them too. While at it also install other shared files which we
    did not install before.
    
    If gdb is built without Python support the python folder does not
    exists.
