LGTM. This seems like a generic way of handling this and is especially useful when using LD_PRELOAD to load custom mutators since iirc LD_PRELOAD doesn't make so much noise when it fails.



================
Comment at: compiler-rt/lib/fuzzer/FuzzerDriver.cpp:201
+    Printf("INFO: found LLVMFuzzerCustomMutator (%p). "
+           "Disabling -len_control by default.\n", EF->LLVMFuzzerCustomMutator);
+  }
----------------
Maybe drop "by default" I don't think they can opt out right?
