- Fixes _dl_exit()
- Implements sleep(3) for !UCLIBC_HAVE_REALTIME
- Implements usleep(3) for !UCLIBC_HAVE_REALTIME
- adds #warning about incorrect posix_fadvise{,64}()
- removes unused and unwanted uselib()
Net outcome is that an allnoconfig with HAVE_SHARED is now about 88k instead
of formerly 130k.

Hi. I found a mismatch between uClibc and kernel in semctl definition.
In uClibc/libc/misc/sysvipc/sem.c:
static inline _syscall4(int, __semctl, int, semid, int, semnum, int, cmd, union semun *, arg);
...
int semctl(int semid, int semnum, int cmd, ...)
...
arg = va_arg (ap, union semun);
...
return __semctl(semid, semnum, cmd, &arg);
But kernel's semctl is:
asmlinkage long sys_semctl (int semid, int semnum, int cmd, union semun arg)
The last argument is an union semun itself, not a pointer to the
union.
Here is a patch.
