To be more precisely, the generated sources also will get built on the host for the cross-platform builds, but during the second stage when the clang toolchain for the target platform is already fully in place. 

As example, here is how Aarch64 lldb-server gets built on x86_64 builder host using just-built clang cross toolchain:
