[ng] texi: "de-prettify" makeinfo command line

This will make some future changes easier.  And anyway, it's usually not
worth to add code complexity to have a slightly pretty output from make;
people who want pretty output should be using "make V=0" anyway ;-)

* automake.in (handle_texinfo_helper): Make definition of $makeinfoflags
less pretty but more easy.
