It's nice to build correct OS-host module depending on compiler tool chain.
But if CLANG9 is a cross-host compiler tool chain, I don't think such need should
be met.
So I would prefer the patch doesn't assume CLANG9 is a hint to build Win host.
Which means when using CLANG9, developer needs to use another macro to
tell build tool which host to build.

Thanks.
