Code review comment for lp:~allison/ubuntu/raring/gpsdrive/merge-debian-patches2

I kept it because of the architecture-specific hints it provides. These weren't random changes, I carefully checked the old Debian versions of the package to make sure the diffs didn't creep in from an improperly made merge.

But, my plan next month is to update the Debian packages to 2.11. (See LP #819145.) After that, we should be able to drop all Ubuntu changes and simply sync the updated package.
