+Subject: [PATCH] Change the install location of _sysconfigdata.py
+
+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.
