Try this one:

g++ tut1.cpp -g -fno-rtti -lclangFrontend -lclangDriver -lclangCodeGen
-lclangSema -lclangChecker -lclangAnalysis -lclangRewrite -lclangAST
-lclangParse -lclangLex -lclangBasic -lclangIndex `llvm-config
--cxxflags --ldflags --libs`

1) You did not specify all of Clang's libs. I don't really know which
ones are actually needed, but the linker should be smart enough to only
include those.

2) Always put the llvm libs after the Clang libs. Clang's libs use the
llvm ones and the linker will only check for open references in libs
given "down" the command line. Took me some time to learn that... ;-)
