Experiment with LTO for OS X and iOS, too

With Clang, LTO means compiling to LLVM intermediate representation
instead of object code, and optimisation and code generation at link
time.

As expected, linking the single executable for the iOS experimental
app takes quite some time (several hours), and in fact it eventually
fails. Hopefully better luck on OS X.

Need to use xcrun to find the right ar and ranlib, too, from the
Xcode toolchain being used.
