[PATCH 3/3] configure.ac: remove --enable-aiglx option

[Emil Velikov]

Presently the option guards both direct and accelerated indirect GLX. As
such when one toggles it off they end up without any acceleration.

Remove the option all together until we have the time to split/rework
things.

Jon, I've not checked the Xwin side of things but considering that the 
option is enabled by default and having it for Xwin only will be 
confusing I've nuked the guards throughout the tree.
