Don't do this here.  It could be in a constructor (i.e. a function someplace
like irt_ppapi.c with __attribute__((constructor))).  But better would be to
have this done only as needed, i.e. on the first call to the manifest loading
stuff.

I implemented this as a constructor.

+    static const char fatal_msg[] =
+        "ppapi initialization (PpapiPluginPreInit) failed.\n";
+    write(2, fatal_msg, sizeof(fatal_msg) - 1);
+    _exit(-1);
+  }
+#endif
