	* sysdeps/mach/hurd/Versions [libc] (GLIBC_2.1.1): Remove
	__libc_clk_tck.
	* sysdeps/mach/hurd/Makefile [$(subdir)==posix] (sysdep_routines):
	Remove clk_tck.
	* sysdeps/mach/hurd/clk_tck.c: Removed.
	* sysdeps/mach/hurd/getclktck.c: New file.
	* sysdeps/mach/hurd/setitimer.c (quantize_timeval): Use
	__getclktck instead of __libc_clk_tck.
	* sysdeps/mach/hurd/bits/time.h: Use __sysconf for CLK_TCK instead
	of __libc_clk_tck.
	* sysdeps/mach/hurd/i386/bits/time.h: Likewise.
