Jeff Johnston f310e8d951 Always assign return value to passed pointer in time function. 
If the passed t pointer is not a null pointer, always assign the return
value to the object it points to, regardless of whether the return value
is an error.

This is what the GNU C Library does, and this is also the expected
behavior according to the latest draft of the C programming language
standard (C11 ISO/IEC 9899:201x WG14 N1570, dated 2011-04-12):

        prototype where second parameter is void *.
        * libc/reent/gettimeofdayr.c (_gettimeofday_r): Change prototype
        accordingly.
        * libc/include/reent.h: Fix prototype for _gettimeofday_r.
        * libc/sys/arm/syscalls.c: Fix gettimeofday function signature.

* libc/time/time.c (time): Do not check for HAVE_GETTIMEOFDAY
        anymore.  Assume there is a gettimeofday syscall.
