Ideally, they should be modified to just use libc++.  I thought that bapt had done this, but I might have misremembered.  Mixing libstdc++ and libc++ is fine if both sit on top of libcxxrt and no standard library types cross library boundaries, but is problematic otherwise (the good news is that you’ll get linker failures if they do try to cross library boundaries, unless they’re thrown as exceptions).
