The undefine of _POSIX_TIMERS in sys/features.h prevents the clock_* and 
timer_* prototypes from beeing exposed on the SPU. Since nanosleep is the only 
function of the _POSIX_TIMERS family which is currently implemented (on the 
SPU) I moved the prototype into the machine header.
In addition spu/times.c implements a stub for the times function declared in 
sys/times.h. The spu/setitimer.c and spu/getitimer.c implement stubs for the 
corresponding functions declared in sys/time.h. 
The attached patch equates the former one except for the Changelog entry of 
include/machine/time.h.
