I don't know of such a flag. My two stage setup actually installs the first stage and then uses the first stage to compile/test the second stage.

Also and for what it's worth, "just built" doesn't really make sense for libcxx since so much of the standard C++ library is at compile time. If you want to avoid two stages and use the latest libcxx, that would require some kind of build flag to override the system C++ headers and use the ones it the git checkout.
