You're supposed to incorporate dpkg-buildflags into the build
yourself, we're not pushing them into all the modules.
>From the changelog:

perl (5.14.2-9) unstable; urgency=low
[...]
  * Modify Config_heavy.pl after the build to remove dpkg-buildflags
    effects on ccflags and lddlflags; we don't want to force them on
    all XS modules at this stage. (See #657853)

This is obviously a tradeoff, but I think it's the "right" way
to do this, just like we didn't want dpkg-buildpackage to force
CFLAGS et al.
