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.
