<pre>About 700 piglit tests regressed on r100. This includes, but is not limited
to:
All 648 subcases of clipflat
fbo-1d
fbo-clearmipmap
fbo-sys-sub-blit
gen-nonzero-unit
...
At least fbo-clearmipmap bisected to the following commit. I did this bisect
using 'git bisect run' with that one test, and I haven't verified all the
others yet.
Tested on:
01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] RV200
[Radeon 7500/7500 LE]
This commit is in Mesa 11.0.

radeon: fix some potential big endian issues
The formats chosen (both by texture format choser, fbo storage allocation)
are different for big endian not just for rgba8 but also lower bit width
formats (why I don't actually know). Even the function to test for
renderable
formats used different formats, however the actual colorbuffer setup did
not.
And the blitter did not take that into account neither.
Untested (what could possibly go wrong...).
