Hi,

Whilst working on the Reproducible Builds effort [0], I noticed
that some packages on i386 are not reproducible as they embed
debugging symbols that vary depending on whether a 32 or 64-bit
kernel is being used.

The root cause is because temporary build directories include the
uname output:

 -'build/bdist.linux-x86_64' does not exist -- can't clean it
 +'build/bdist.linux-i686' does not exist -- can't clean it

This value comes from ``sysconfig.get_platform``:

  http://sources.debian.net/src/python2.7/2.7.12-2/Lib/sysconfig.py/#L572-L584
  http://sources.debian.net/src/python3.5/3.5.2-3/Lib/sysconfig.py/#L646-L658

We can easily fix it for all dh-python packages by exporting
_PYTHON_HOST_PLATFORM in the environment (if not set!) to something
that does not vary depending on the kernel. For example, combining
DEB_TARGET_ARCH_OS and DEB_TARGET_ARCH (eg. "linux-i386").

Patch attached.

There hasn't seem to be any update on this bug in 63 days, in which
time the Reproducible Builds effort has come on a long way. :)

Would you consider applying this patch and uploading?
