[issue20213] Change the install location of _sysconfigdata.py

[Thomas Petazzoni]

New submission from Thomas Petazzoni:

The _sysconfigdata.py module contains definitions that are needed when building Python modules. In cross-compilation mode, when building Python extensions for the target, we need to use the _sysconfigdata.py of the target Python while executing the host Python.

However until now, the _sysconfigdata.py module was installed in build/lib.<arch>-<version> directory, together with a number of architecture-specific shared objects, which cannot be used with the host Python.

To solve this problem, this patch moves _sysconfigdata.py to a separate location, build/sysconfigdata.<arch>-<version>/, and only this directory gets added to the PYTHONPATH of the host Python interpreter when building Python modules for the target.
