* sysdeps/generic/bits/time.h: Replaced with contents of the
	sysdeps/unix/sysv/linux/i386/bits/time.h file.  All the following
	files were identical except for the absence of CLOCK_THREAD_CPUTIME_ID
	and CLOCK_PROCESS_CPUTIME_ID in .../linux/bits/time.h; adding these
	macros is ok even for architectures that don't now implement them.
	* sysdeps/mach/hurd/bits/time.h: File removed.
