This was just a temporary change to see how it works.

That explains why MCJIT test executable
(build/unittests/ExecutionEngine/MCJIT/MCJITTests) was an X86 binary in my
case. It appears to me that these tests will always fail for
cross-compilation unless modified for remote execution.

I noticed "TARGET_HAS_JIT" flag in Makefile.config. Can I use this flag to
exclude MCJIT and JIT tests when not set? This will be a simpler change than
modifying the macro.

Thanks,
