* sysdeps/unix/sysv/linux/poll.c: Don't define as stub. Use
simulation of system call using select.
* sysdeps/unix/sysv/linux/signal.c: Use POSIX implementation.
* sysdeps/unix/sysv/linux/statbuf.h: Define _STAT_VER.
* sysdeps/unix/sysv/linux/i386/sigaction.c: Correct parameter
name usage (new->act, old->oact).
Correct asm statement because of gcc strangeness.
* sysdeps/i386/i586/strchr.S: Correct typos: cmp -> cmpb.
* sunrpc/clnt_perr.c: Remove declaration of sys_errlist. They
conflict with the ones in stdio.h.
* string/tester.c: %Z is no complete format. Change to %Zd.
* sysdeps/mach/hurd/symlink.c (__symlink): Ditto.
