[1.1] fixes for g77 dvi target

[Dave Love <d dot love at dl dot ac dot uk>]

`make f/g77.dvi' currently doesn't work at all, per a report to
bug-gcc inter alia.  The invocation of texi2dvi is wrong (though
there's a -I arg in the development version) and a Texinfo bug gives a
TeX error anyhow.  I'll take out the kluge for the TeX error in favour
of something else when there's an official fix for texinfo.tex, but
this will get it working for the release.

Craig agrees with this on both branches.  Is that OK?

1998-07-30  Dave Love  <d.love@dl.ac.uk>

	* Make-lang.in (f/g77.dvi): Replace non-working use of texi2dvi
	with explicit use of tex.
	(f77.mostlyclean): Remove TeX index files.

	* g77install.texi (Prerequisites): Kluge round TeX lossage with
	hyphen in @value in @code.
