Just FYI, I backed out the SS12 patches until I had the same as you two, but still got the same error. I then replaced libtool with the one in /opt/kdebld/bin and it compiled and linked just fine. I then reapplied the latest C, C++, and common compiler patches for SS12 and it also recompiled fine with that other libtool.
