Failed to use afl-clang-fast

[Keenan]

There's no afl-clang-fast or afl-clang-fast++ after run the compile.sh:

pushd fuzz/afl
make clean
make CC=clang-6.0
#pushd llvm_mode
#make clean
#make CC=clang-6.0 CXX=g++ 
#popd
popd

when I tried to compile them by myself I got that two binary but failed with afl-llvm-pass.so

When try to Instrument v8:

         Location : find_obj(), afl-clang-fast.c:90

fixed with the following line in the llvm_mode/Makefile

CLANG_CFL    = `$(LLVM_CONFIG) --cxxflags` -Wl,-znodelete -fno-rtti -fpic $(CXXFLAGS)

But still failed when instrument v8
