Sorry about that. I suspect it was working accidentally before (neither depending on clangBasic nor anything tablegen related is the right way for us to resolve a standard library dependency).
In any case it's not a *functional* change.

Do you want help resolving this? Can you provide more details about the setup?
My guess is that the build is specifying libc++ somehow but it's neither installed systemwide (ld.so.cache) nor is LD_LIBRARY_PATH set.
