Bug Description

Hi,
while working on a new DPDK I was wondering how I'd broken the non DPDK arches as well.
TL;DR it is currently FTBFS as-is in artful.

Full build log:
https://launchpadlibrarian.net/320055040/buildlog_ubuntu-artful-amd64.openvswitch_2.7.0-0ubuntu2_BUILDING.txt.gz

ovs/_json.c:1:20: fatal error: Python.h: No such file or directory

Ok, the gcc error seems to be "normal"?
Maybe it just went undetected so far.

The good build has this as well:

 #include "Python.h"

Once per python version, the openvswitch build automatically does:
WARNING: The C extension could not be compiled, speedups are not enabled.
Failure information, if any, is above.
Retrying the build without the C extension.

Need to discuss if that is ok or another issue in itself, but that means the FTBFS atm is only about:
GOOD
running install_scripts
install -D _dpdk/vswitchd/ovs-vswitchd \
        /<<PKGBUILDDIR>>/debian/openvswitch-switch-dpdk/usr/lib/openvswitch-switch-dpdk/ovs-vswitchd-dpdk

BAD
running install_scripts
/bin/sh: 2: cd: can't cd to python
debian/rules:84: recipe for target 'override_dh_install' failed

To ensure debugging isn't too easy a local SBUILD just worked as-is, while reliably failing on Launchpad.

Local repro worked, it seems it is due to two python's being in proposed at once.
The first cd works, but the second fails ... trying a fix now.

Confirmed, pyversions provides two values for
PYTHON3S:=$(shell py3versions -vr)

$ py3versions -vr
3.6 3.5

Fix is working, but I need to fix up more around DPDK and Arm until I push mine together with the others.

Please let me know if that is any more urgent for you.

FYI - still waiting on upstream fix in regard to arm support to be accepted to be "one" upload for the changes.
