Review Comment:
   I am building the cpp tests on aarch64 instead of cross-compiling, and in order to build (and run) the tests, I need the LLVM backend enabled.  I am running this config file on the aarch64 Jenkins node before building the tests.
   
   The reason I am not cross-compiling the cpp tests is that I would need to cross-compile gtest beforehand.
