	* sysdeps/unix/sysv/linux/alpha/wait4.S: Ditto.

	* sysdeps/unix/make-syscalls.sh: Make versioned symbols only
	for shared library.

	* libc.map (adjtime, __adjtimex, adjtimex): Added for GLIBC_2.1.

	* sysdeps/unix/sysv/linux/alpha/Makefile (sysdep_routines):
	Added adjtimex and old_adjtimex.

	* sysdeps/unix/sysv/linux/alpha/syscalls.list (old_adjtimex):
	New.
	(osf_settimeofday, osf_getitimer, osf_setitimer, osf_utimes,
	osf_getrusage, osf_wait4): Added __xxxx symbol for GLIBC_2.0.

	* sysdeps/unix/sysv/linux/alpha/getitimer.S: Make versioned
	symbols only for shared library.
	* sysdeps/unix/sysv/linux/alpha/getrusage.S: Likewise.
	* sysdeps/unix/sysv/linux/alpha/gettimeofday.S: Likewise.
	* sysdeps/unix/sysv/linux/alpha/select.S: Likewise.

	* sysdeps/unix/sysv/linux/alpha/utimes.S: Likewise.
	* sysdeps/unix/sysv/linux/alpha/wait4.S: Likewise.

	* sysdeps/unix/sysv/linux/alpha/getitimer.S: Fix ENOSYS branch.
	* sysdeps/unix/sysv/linux/alpha/getrusage.S: Likewise.
	* sysdeps/unix/sysv/linux/alpha/gettimeofday.S: Likewise.
	* sysdeps/unix/sysv/linux/alpha/select.S: Likewise.
	* sysdeps/unix/sysv/linux/alpha/setitimer.S: Likewise.
	* sysdeps/unix/sysv/linux/alpha/settimeofday.S: Likewise.

	* sysdeps/unix/sysv/linux/alpha/wait4.S: Likewise.

	* sysdeps/unix/sysv/linux/alpha/wait4.S: Check the correct
	rusage pointer.

	* sysdeps/unix/sysv/linux/adjtime.c (TIMEVAL, TIMEX, ADJTIMEX):
	New macros.
	(__adjtime): Use TIMEVAL, TIMEX and ADJTIMEX instead of timeval,
	timex and __adjtimex, respectively.

	* sysdeps/unix/sysv/linux/alpha/adjtime.c: New.

	* sysdeps/unix/sysv/linux/alpha/adjtimex.S: New.
