[Pixman] [cairo] Pixman concurrency problem on iOS/ARM

Configuration script detects none, and in general does not work with iOS
(fails on all sorts of obvious things).

I have manually configured it to use TLS. Pixman is compiled as a static
library. Don't know if this is correct.
I can try pthread_setspecific if you feel it might make a difference.
