This is dpkg-buildflags:

dpkg (1.17.11) unstable; urgency=low
  [...]
  * Add support for new hardening build flag stackprotectorstrong in Debian
    and derivatives, enabled by default. It will fallback to stackprotector
    when the former is not functional or disabled by the user.
    Thanks to Romain Francoise <rfrancoise at debian.org>.

I didn't look at the code, but the changelog says:

schroot (1.7.2-1) experimental; urgency=medium
  [...]
  * debian/rules:
    - Build using g++-4.8, needed for C++11 compatibility until the
      default compiler for all architectures supports C++11.

Now that GCC 4.9 is the default compiler, I guess this change should be 
reverted.
