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}
