The change made to the building script to include 64-bit compilation of 
the iOS engines in LC 7.0.2-rc-1 had not not been committed, and we 
built LC 7.0.2-rc-2 from another machine. Hence the iOS engines in LC 
7.0.2-rc-2 do not have the 64-bit architecture (which we realised too late).

Also, we are aware of the minimal system version issue, and are 
currently in the process of fixing it.
