Bug#841827: liborc-0.4-dev: cannot run orcc during cross compilation of reverse dependencies

[Helmut Grohne]

Package: liborc-0.4-dev
Version: 1:0.4.26-1
Tags: patch
User: helmutg at debian.org
Usertags: rebootstrap
Control: affects -1 + src:buzztrax src:ffmpeg src:gnuradio src:gst-libav1.0 src:gst-plugins-base1.0 src:gst-plugins-good1.0 src:libquicktime src:lives src:mplayer src:pulseaudio src:schroedinger src:uhd

Cross compiling the packages listed above results in a failure to
execute orcc. orcc resides in liborc-0.4-dev which is usually a host
architecture dependency and thus orcc also is a host architecture
executable, which cannot be run.

I propose splitting liborc-0.4-dev into liborc-0.4-dev-bin. The latter
would take over the binaries from liborc-0.4-dev. Since at least
orc-bugreport looks like it has architecture-dependent output, I don't
think we can mark it Multi-Arch: foreign. Thus I propose marking
liborc-0.4-dev-bin Multi-Arch: allowed and having liborc-0.4-dev depend
on liborc-0.4-dev-bin:any. Practically, this results in
liborc-0.4-dev-bin being installed for the build architecture and thus
fixing cross builds.

Please consider applying the attached patch.  If you have more insight
into what these binaries do, consider using Multi-Arch: foreign if that
is appropriate. You may have to adapt the versions listed in Breaks and
Replaces.

+Description: Library of Optimized Inner Loops Runtime Compiler (development tools)
+ Orc is a library and set of tools for compiling and executing
+ very simple programs that operate on arrays of data.  The "language"
+ is a generic assembly language that represents many of the features
+ available in SIMD architectures, including saturated addition and
+ subtraction, and many arithmetic operations.
+ .
+ This package contains the development tools, and should not be
+ installed directly.
