This appears to be caused by your addition of -stdlib=libc++ -std=c++11 to your CXXFLAGS. So, first of all, thank you for testing libc++!
I tested with libc++ while I was developing dtc, but then was building with libstdc++ while I was removing extraneous includes. Unfortunately, libstdc++ leaks a load of C headers, whereas libc++ is very careful not to. I've now (r245839) explicitly included everything so it now builds with libc++ and in C++11 mode.
Thanks for the report,
David
