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.
This was fixed by python3-use-CROSSPYTHONPATH-for-PYTHON_FOR_BUILD.patch
but it broke _ctypes build and then the CROSSPYTHONPATH was
set back to the default paths by the commit:
"c254807 python3-ctypes: Fix cross compilation for arm targets"
So correct the above patch and export the correct path
for CROSSPYTHONPATH, to fix both of the issues.
And remove the python3-setup.py-no-host-headers-libs.patch,
it was needed since the above inappropriate patch causes
setup.py gets data from the native _sysconfigdata and
introduce host paths, it's not needed any more with
this fix.
