gnome-doc-utils : Support for new ppc64le arch

[Chandan <chandand linux vnet ibm com>]

Hi Shaun,

We are adding support for new ppc64le (IBM powerPC Little Endian)
architecture as part of which we are looking at all the packages that
need update.
I was looking at gnome-doc-utils (from repository
git://git.gnome.org/gnome-doc-utils and gnome-doc-utils-0.20.10 as well)
and was failed to build gnome-doc-utils on ppc64le machine because of
outdated config.guess.

Automake version of 1.13.4 onward has the support of ppc64le.
 
Would it be possible for you to spin up a newer version of
"gnome-doc-utils" by using the automake-1.13.4 or above?

I can help to validate the new release tarball of the "gnome-doc-utils"
works well by compiling on ppc64le machine.

Appreciate your response.

Thanks,
Chandan
