Long time listener, first time caller (I hope I did this all correctly :)  I am
also trying to develop my own patch for the src rpm to do this, so if the
package maintainers could give me a little help with that, it would be appreciated.

did not mean to close.. reopened.

If you have patches to add pkgconfig files to X.Org CVS head, please submit
them in X.Org bugzilla at http://bugs.freedesktop.org in the 'xorg' component
for consideration for the next release of Xorg by X.Org developers.

When X.Org provides pkgconfig files in an official upstream stable X.Org
we'll pick it up automatically as part of our development process.  This
is preferred over us manually adding them in order to ensure various
upstream applications do not start requiring Red Hat specific files to
build, which are not supplied in the upstream X sources.
