I believe that a close relationship to binutils is just a minor problem for users running stable version. It is very unlikely that in the updates for stable version of Debian/Ubuntu distribution (or backports) will be updated binutils, which would break dependencies.
The problem is therefore only applies to users who use testing and unstable distributions. For such versions of distributions is not possible to release the "final" versions of TDE, because any time something can go wrong. I assume that users will always have to use either nightly-builds or preliminary updates for stable TDE branch. As was my ppa for v3.5.13.x branch.
I any case, if backtraces is good even without the lib bfd, we can turn off WITH_LIBBFD and remove binutils- dev from tdelibs-trinity build-deps and tdelibs14-trinity-dev dependencies. To me this seems appropriate.

You have more experience than me, so I leave the choice to you and Tim. Both choices are ok for me. I usually do a full rebuild every month or two, so in the worst case I just hold up the binutils update for a few weeks.
