needless error in "missing makeinfo"

[Bruno Haible]

When "missing" is called to emulate makeinfo and the texi file does not have
a @setfilename command, "missing" calls "touch" without arguments, which
leads to exit code 1. Seen with gettext's nls.texi.

Here is a fix, relative to automake-1.9.4.

        * missing (makeinfo): Don't call touch without arguments if the source
        texinfo file doesn't contain a @setfilename command.
