macOS: Prevent Xcode 9.3 build warnings
This PR solves #12867 (needs to run autogen.sh && ./configure)
clang (Apple LLVM version 9.1.0 (clang-902.0.39.1)) warns unused
argument '-pie' during compilation.
So we check for warnings in the test using $CXXFLAG_WERROR.
Windows is alse default-pie and was special-cased because it also
warned, but we can also eliminate that case if warnings are caught.
