bcain added a comment.

IIRC, before this change we could use `use_system_cxx_lib` with LLVM_LIT_ARGS to indicate "do not test the just-built libc++, instead test the libc++ build toolchain's libc++".  Perhaps this is what is meant by "back deployment"?

Or possibly this change to `use_system_cxx_lib` happened in an earlier commit?

But in any case, it seems like that feature is no longer present because `stdlib=llvm-libc++` can't distinguish between the one from the build toolchain and the just-built library, right?  What's an appropriate/recommended way to make this sort of change?
