It also changes the stdlib from libstdc++ to libc++ (explicitly for Hotspot and implicitly everywhere else). This change is necessary to keep up with newer toolchain versions on Macosx where using the old and no longer maintained libstdc++ has been deprecated. This is done in preparation for bumping the preferred Xcode version used for builds at Oracle.
