Bug#1123014: ann FTCBFS: python3 build dependency not installable for the host architecture

[Helmut Grohne]

Source: ann
Version: 1.1.2+doc-9
Tags: patch
User: debian-cross at lists.debian.org
Usertags: cross-satisfiability

ann cannot be cross built from source, because it Build-Depends on the
host architecture python3 interpreter package. Attempting to install it
fails the byte compilation step. ann really wants to run python3 during
build to perform the cctbx source conversion, so it really wants a build
architecture python3. Thus, the dependency should be annotated :native.
I'm attaching a patch for your convenience.
