I'm having issues compiling the latest HEAD of libFuzzer, let's use
a fixed version (29d1659edabe4ba2396f9697915bb7a0880cbd2f) for now
[ -e libFuzzer.a ] && exit 0
[ -d Fuzzer ] || git clone https://chromium.googlesource.com/chromium/llvm-project/llvm/lib/Fuzzer
+cd Fuzzer
+git checkout 29d1659edabe4ba2396f9697915bb7a0880cbd2f
+cd ..
Fuzzer/build.sh
