[Ves] Compiling VES on iOS

[Casey Goodlett]

Yes you are using a separate compiler here for the simulator and device
builds.

Try commenting out both uses of find_program at the start of the simulator
toolchain.  In newer xcode I think we should ignore this emebbeded g++
executable, buts its needed on old versions of xcode.
