[PATCH] D83494: [libFuzzer] Link libFuzzer's own interceptors when other compiler runtimes are not linked.

Addressed Matt's comments.

A major change in this round that needs explanation is introduction of FuzzerPlatform.h. Previously I defined `strstr` and `strcasestr` with `extern "C++"` to workaround conflicting definition errors resulting from including <string.h>. But since including it is not necessary when compiling this interceptor module, this patch now separates out platform related macros from FuzzerDef.h into FuzzerPlatform.h, and the module includes FuzzerPlatform.h, not FuzzerDef.h.
