* 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.
* sysdeps/unix/sysv/linux/bits/time.h: File removed.
* sysdeps/unix/sysv/linux/i386/bits/time.h: File removed.
* sysdeps/unix/sysv/linux/ia64/bits/time.h: File removed.
* sysdeps/unix/sysv/linux/sparc/bits/time.h: File removed.
* sysdeps/unix/sysv/linux/x86_64/bits/time.h: File removed.
