python3: python3: Fix build error x86->x86

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.

Fixes:

Illegal instruction (core dumped)
Makefile:625: recipe for target 'sharedmods' failed
make: *** [sharedmods] Error 132
make: *** Waiting for unfinished jobs....
