--- Comment #2 from Kostya Serebryany <kcc at google.com> ---
1. you are using a very old libFuzzer and much newer clang. This won't work. 
Please use the fresh and matching versions of both. 

2. -lcurl  is not going to work. If you want to fuzz curl you need to
instrument it itself, not link the system library (that is not instrumented).
Take a look at the rest of the files in
https://github.com/google/oss-fuzz/tree/master/projects/curl
