FWIW, I am getting the same linker errors on OS X:

Undefined symbols for architecture x86_64:
  "_LLVMInitializeHexagonAsmPrinter", referenced from:
      LTOCodeGenerator::LTOCodeGenerator() in LTOCodeGenerator.o
  "_LLVMInitializeHexagonTargetMC", referenced from:
      LTOCodeGenerator::LTOCodeGenerator() in LTOCodeGenerator.o
      LTOModule::makeLTOModule(llvm::MemoryBuffer*, std::string&) in LTOModule.o
  "_LLVMInitializeHexagonTarget", referenced from:
      llvm::InitializeAllTargets() in LTOCodeGenerator.o
  "_LLVMInitializeHexagonTargetInfo", referenced from:
      llvm::InitializeAllTargets() in LTOCodeGenerator.o
ld: symbol(s) not found for architecture x86_64

Are you building with CMake or configure?
