As of 3.14.0, Python's sysconfig module looks for _PYTHON_PROJECT_BASE
to be set when cross-compiling, or otherwise it'll find and use the
native interpreter's paths when calling get_path() and filling out
_CONFIG_VARS. Set _PYTHON_PROJECT_BASE to "${B}" in
python3targetconfig's setup_target_config() to help avoid issues with
incorrect paths in rpm and other recipes that depend on this class.
