it's a bit old, but the srpm contains the patch I made to xbmc to
build it before:
http://people.freedesktop.org/~robclark/xbmc-repo/source/SRPMS/

I'm sure the patch won't apply cleanly as-is anymore but it should be
straightforward enough to understand what change in configure script
was needed..
