 ceph (0.26~rc-1) experimental; urgency=low
 
   * Make ceph x86 and x64 only due to dependency on architecture dependent
     google-perftools (closes: #614890).
   * Correct section of libcrush1, librados1, librbd1 and libceph1 to libs.
+  * Make Ceph cross buildable (closes: #618939), thanks to Hector Oron.
