[LLVMdev] Android build patch

[jameslyon0 at gmail.com]

I don't have another hardware ARM system, but I got it working under a qemu
ARM system before trying Android and there are no issues there. I'm only
putting one module in the JIT, so that shouldn't be the issue; thanks for
the registerEHFrame suggestion though. I won't get time to try it until the
weekend though.
