I found that orbit2 build will give us orbit-idl-2 binary,it means while
building orbit2 it will build for target.

One more point if any other application want's to use orbit-idl-2 then
in this case it is from host machine (/usr/bin/orbit-idl-2) or it should
be used from the result of orbit2 cross build.

Please correct me if i am wrong at any point for my better
understanding.
