Large part of this change is required due to https://code.google.com/p/android/issues/detail?id=61799 dlsym() crashes when symbol resolution fails, which means we have to limit the interceptor list instead of relying on runtime detection. There are minor differencies in system headers, too. llvm-svn: 212273
