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;
 }
 
 // Set the incremental linking mode to INCREMENTAL_FULL.  Used when
 // the linker determines that an incremental update is not possible.
 // Returns false if the incremental mode was INCREMENTAL_UPDATE,
 // indicating that the linker should exit if an update is not possible.
