+libav (6:11.1-1+rpi1) jessie-staging; urgency=medium
+
+  * Add special case handling for Raspbian (and any derivatives thereof) (Closes: 738760)
+    + Disable armv6t2
+      - note: the thumb2 variant of arv6 seems to be very rare, the Pi certainly
+        doesn't have it.
+    + Disable neon in the main build.
+    + Don't build a seperate neon flavour either.
