Try putting your libraries in the following order: -lclangCodeGen
-lclangAnalysis -lclangRewrite -lclangSEMA -lclangAST -lclangParse
-lclangLex -lclangBasic -lLLVMBitWriter -lLLVMBitReader -lLLVMCodeGen
-lLLVMTarget -lLLVMSupport -lLLVMCore -lLLVMSystem -lpthread -ldl -lm

I'm not entirely sure how clang avoids running into this; I don't know
very much about linker magic.
