Message:

Implement clock()

Newlib uses _times_r() in clock(). The problem is that the _times_r()
clock frequency is defined by sysconf(_SC_CLK_TCK). The clock frequency
of clock() is the constant CLOCKS_PER_SEC.

FreeBSD uses getrusage() for clock(). Since RTEMS has only one process,
the implementation can be simplified.

Update #3121.
