[Reproducible-builds] Bug#792867: FTCBFS: uses wrong architecture Python

Dear bsdmainutils maintainers,

While trying to cross build bsdmainutils, I noticed that it was
installing the host architecture python and python-hdate. It then tries
to execute that Python as a build tool, which fails, because the host
architecture is usually not executable during cross compilation.

Since python and python-hdate are only used as build tools, the correct
solution is to always install them for the build architecture. This can
be reflected in the Build-Depends by annotating those packages with
":native".

The attached patch implements that proposal. Please consider applying
it. The ":native" is supported in apt and dpkg since wheezy. If in
doubt, don't hesitate to ask for details on the identified problem or
the proposed solution.

As an aside note, I question the use of python-hdate to compute the
Jewish calendar:
 * Since the build date is used to select the year of the calendar file,
   the package is not reproducible. (Ccing the reproducible people)
 * The last build happened in 2014, so the installed calendar is no
   longer useful for day to day use (neither in stable nor in unstable).

Helmut
