Chris Wilson 95374225e8 Enable compilation on non-Intel, non-DRM systems.
A few of the tools can be performed post-mortem from a different system,
so it is useful to be able to compile those tools on those foreign
systems. Obviously, any program to interact with the PCI device or talk
to GEM will fail on a non-Intel system.

/** @file gem_tiled_blits.c
*
* This is a test of doing many tiled blits, with a working set
* larger than the aperture size.
*
* The goal is to catch a couple types of failure;
* - Fence management problems on pre-965.
* - A17 or L-shaped memory tiling workaround problems in acceleration.
*
* The model is to fill a collection of 1MB objects in a way that can't trip
* over A6 swizzling -- upload data to a non-tiled object, blit to the tiled
* object. Then, copy the 1MB objects randomly between each other for a while.
* Finally, download their data through linear objects again and see what
* resulted.
