Please convert glibmm2.4 for multiarch

[Evan Broder]

Attached is a patch to gtkmm2.4 which transitions it to use multiarch library paths.

The patch also marks the -dev package as multi-arch: same, which is safe as none of the header files are generated at build time, so they should be identical across architectures. As libglib2.0-dev is not marked multi-arch: same, libglibmm-2.4-dev will not currently be multi-arch installable, but will immediately become so if libglib2.0-dev is converted.

The most significant blocker to converting packages to multiarch is the presence of .la files which reference a library in its dependency_libs line. Debian has made cleaning up these .la files a release goal, and is tracking the presence of such problematic .la files at <http://release.debian.org/~aba/la/current.txt>.

For some reason glibmm2.4 isn't listed in that file. However, as the rest of the gtkmm stack lists python-visual and subtitleeditor, I assume that those reference glibmm2.4 as well. subtitleeditor has already been fixed and both Debian and Ubuntu, and I uploaded a fix for python-visual a few days ago, so by that metric this conversion should be safe.

Steve Langasek has suggested that having debhelper substitute in the pre-dependency through ${misc:Pre-Depends} is better than hard-coding it so we can drop it in the future, so here's a new patch that does that.

This bug was fixed in the package glibmm2.4 - 2.31.2-0ubuntu2

---------------
glibmm2.4 (2.31.2-0ubuntu2) precise; urgency=low

  * Convert to multiarch:
    - Pass --libdir with multiarch path to configure
    - Adjust .install files to refer to /usr/lib/subdirs
    - Add multiarch Pre-Depends
