[PATCH] D12679: [CMake] Flag recursive cmake invocations for cross-compile

The motivation here is to enable LLVM_OPTIMIZED_TABLEGEN in LLILC, since we see a **dramatic** improvement in build time with it (measured on my laptop, clean debug build time drops from 4 hours to 15 minutes).  So I picked reviewers based on http://reviews.llvm.org/D7349, which added LLVM_OPTIMIZED_TABLEGEN.  I'm certainly open to alternative approaches, this was the cleanest I came up with short of redoing how crosscompile is handled.
