From: Jackie Huang <jackie.hu...@windriver.com>
If the target and host have the same type, the system
may try to execute the instructions from the target
version. This can lead to illegal instructions
as well as the wrong copy of the code running.
Add CROSSPYTHONPATH for PYTHON_FOR_BUILD and export
the correct path to fix it.

+configure.ac: add CROSSPYTHONPATH into PYTHONPATH for PYTHON_FOR_BUILD
+
+When building x86->x86 the system will try to execute .so and related items
+from the default PYTHONPATH. This will fail if the target CPU contains
+instructions that the host CPU does not have, add CROSSPYTHONPATH
+into PYTHONPATH so we can prepend the list to find correct libs.
