Error in patch to not use lang/Makefile.in

[Richard Kenner]

This part of this change:

2000-10-27  Zack Weinberg  <zack@wolery.stanford.edu>

	* configure.in: Do not include $srcdir/$s/Makefile.in in
	all_lang_makefiles, but do include $outputs.  

is wrong.

$outputs will be language/Makefile, but this is going to become a dependency
for Makefile, but the latter is made first.  Hence this is an infinte loop.

I think this code needs to add lang/Makefile.in if it exists.

Zack, can you fix this?
