[Clfs-support] Make error in diffutils-3.6

[Daniel GSJ]

Hello,

I have found an error during the make step of diffutils (Chapter 6 of CLFS).
There is a deviation respect of the original book, I'm trying to install
version 3.6 instead of 3.3.

In fact, I'm trying to build CLFS with the most updated versions of the
programs. The installation according to Chapters 5 and 6 (with updated
versions) seems to work fine, except for diffutils and texinfo (that I'll
comment in another thread). Please see the details below.

Thank you in advanced for your help.
