Burn troublesome debugging code with fire.

This wasn't doing anything on any platform, even in debug mode, it was
just in upstream in case someone wanted to debug xbrz.

Removing it, will have to remember to remove again when syncing upstream.
It makes Linux still break and does not help cross-compat.
