Looks still broken.  Won't build with eglibc 2.11.2 on a debian box.

coreutils/lib.a(date.o): In function `date_main':
/home/cii/DEVEL/busybox-git/busybox/coreutils/date.c:211: undefined
reference to `clock_gettime'
collect2: ld returned 1 exit status
make: *** [busybox_unstripped] Error 1

Other code around similar call I find:

./libbb/time.c: if (syscall(__NR_clock_gettime, CLOCK_MONOTONIC, ts))
./libbb/time.c:         bb_error_msg_and_die("clock_gettime(MONOTONIC) failed");
./runit/runsv.c:        syscall(__NR_clock_gettime, CLOCK_REALTIME, ts);
./coreutils/date.c:             clock_gettime(CLOCK_REALTIME, &ts);

Any ideas?
