[PATCH] D16158: [CMake] Add clang's targets to LLVM's export set when not building standalone

CMake freaks out in trivial cases like:

> cmake -G Ninja -DLLVM_ENABLE_PIC=Off -DLLVM_INSTALL_TOOLCHAIN_ONLY=On ../llvm

This is a result of static ink dependencies not all being part of the same export group, and was caused by r249935.
