CMake and autotools disagree on what "host" means in a cross-compilation context. Autotools (and lit) take it to be the machine the binaries being compiled now will run on. CMake takes it to be the machine actually compiling the binaries now. This change makes lit.site-cfg more consistent between autotools and CMake, allowing lit tests (particularly in ExecutionEngine) to run correctly when cross-compiled with CMake git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@175179 91177308-0d34-0410-b5e6-96231b3b80d8
