I wonder if there's a clearer way to do this; it took me a while to realize that
the check above is actually testing x86-64.

       for exe in ${EXECUTABLES}; do
         local exe_noext=${exe%.*}
-        WriteLauncherScriptPNaCl ${exe_noext} \
-            $(basename ${exe_noext}.${arch}.nexe) ${arch}
+        WriteLauncherScript ${exe_noext} $(basename ${exe_noext}.${arch}.nexe)
       done
-      make check EXEEXT=
+      LogExecute make check EXEEXT=
     done
-  else
-    make check EXEEXT=
   fi
