avoid warning from makeinfo

[Bruno Haible]

Just saw this in the doc directory:

$ make html
makeinfo --no-split --html -o gnulib.html gnulib.texi
/packages/GNULIB/gnulib-work/doc//gnulib.texi:597: warning: node `Function 
Substitutes' has been referenced 1119 times.

I don't know what the purpose of this warning is, therefore I'm shutting it
up:
