FYI: this will likely not work with pnacl

MIPS has __start as default entry symbol (other architectures usally has _start)
in Linux. This is needed for GOLD. We can resolve any PNaCl issue on a different
place.

+	ret = "__start";
+      else
       // FIXME: Need to support target specific entry symbol.
-      ret = "_start";
+	ret = "_start";
     }
   return ret;
 }
