[Daniel van Vugt <daniel.van.vugt@xxxxxxxxxxxxx>]

Looks like the offending change was:

gcc-4.9 (4.9.1-14ubuntu2) utopic; urgency=medium

  * Merge with Debian; remaining changes:
    - Build from upstream sources.

gcc-4.9 (4.9.1-14) unstable; urgency=medium

  * Update to SVN 20140912 (r215228) from the gcc-4_9-branch.
  * Update the Linaro support to the 4.9-2014.09 release.
  * Fix installation of the libstdc++ documentation. Closes: #760872.
