look at how lli is implemented (tools/lli/lli.cpp) you should be able to
see calls to "setUseMCJIT" which you'll want to duplicate in your code.

Yeah, I actually thought I was using the MCJIT (turns out you actually need
to include MCJIT.h, not just call setUseMCJIT() on your EngineBuilder,
d'oh!), and now I get presented with:

LLVM ERROR: Target does not support MC emission!

So looks like it's back to the drawing board, and I'll need to port a later
version of LLVM to Android. Thanks for the help!
