stream unbuffered.
* rt/Makefile (tests): Add tst-clock.
Add rules to build tst-clock.
* rt/tst-clock.c: New file.
* sysdeps/unix/i386/i586/clock_getres.c: Correct expression to decide
about initialization of nsec.
* sysdeps/unix/i386/i586/clock_gettime.c: Correct expression to decide
about initialization of freq. Set retval to zero if successful.
* sysdeps/unix/sysv/linux/i386/get_clockfreq.c: Cache result.
