[patch] fix thread test cases for solaris.

[Andreas Tobler]

Hi all,

The below test cases fail under sparc-solaris10, undefined reference to 
sched_yield or nanosleep. Those are part of librt.

This simple patch makes these test cases compile and run under 
sparc-solaris10. (Not supported under solaris8)

Ok for trunk?

Thanks,
Andreas
