+gdb (7.12-6.deb7moz1) wheezy; urgency=medium
+
+  * Mozilla backport for wheezy.
+  * debian/rules, debian/control: Don't use libbabeltrace, which is not
+    available on wheezy.
+  * debian/rules:
+    - Use DEB_HOST_{ARCH,GNU_TYPE} instead of DEB_TARGET_{ARCH,GNU_TYPE}
+      because the latter is not available on wheezy.
+    - Don't pass --dbgsym-migration to dh_strip, it's not supported on
+      wheezy's debhelper.
