This change was intentional.  I should have made the change
in its own commit, but hey, I'm not perfect.

>From the pkg-config man page:

  The default directory will always be searched after searching

Putting pkg-config files in datadir is perfectly valid.  Most
pkg-config files are in libdir because they reference stuff
that's installed in libdir.  (This is important on systems
that have parallel-installable 32-bit and 64-bit versions of
libraries in /usr/lib and /usr/lib64.)

Since everything gnome-doc-utils.pc references is in datadir,
it makes sense for the pkg-config file to be in datadir as
well.  By the way, before I made this change, both Fedora and
Ubuntu were patching gnome-doc-utils to put the pkg-config
file in datadir.

Is this change causing any real problems?
