Bug#1124530: libplacebo FTCBFS: unsatisfiable Python Build-Depends

[Helmut Grohne <helmut@subdivi.de>]

Source: libplacebo
Version: 7.351.0-2
Tags: patch
User: debian-cross@lists.debian.org
Usertags: cross-satisfiability

libplacebo cannot be cross built from source, because it Build-Depends
on a few Python packages and implicitly requests them for the host
architecture. They're meant to be run during build, so it should be
requesting them for the build architecture by annotating them :native.
Once doing so, libplacebo cross builds successfully. I'm attaching a
patch for your convenience.
