[Pixman] mmx build regression

[Jeremy Huddleston]

I just got my tinderbox back up today and noticed this build regression in pixman.  I haven't looked into it yet, but git-log blames Matt ;)  

http://tinderbox.x.org/builds/2012-02-22-0001/logs/pixman/#build

The warnings are harmless.  I wish the error was more verbose, but that's all I got.  I'll try bisecting when I get a chance, but I'm overloaded right now and wanted to report this since you might have an idea before I get some time.
