  This is an updated version of my previous patchset [1].  The main
changes are the one noted by Carlos's review:

  - Drop the libpthread abi change for mips (not really anymore
    due the libpthread move to libc).
  - Handle the POSIX requirement for getsockopt fallback.
  - Add extra members to struct stat, msqid_ds, semid_ds, and
    shmid_ds.
  - Remove the extra 'shm-directoy' make rule.
  - Replace all "64 bit" with "64-bit".  The only I didn't change is
    at the manual because it mimics what _LARGEFILE64_SOURCE and
    _FILE_OFFSET_BITS already do (I think an extra patch would be
    better to fix it).

As before this patchset add support for 64 bit time on ABIs which only
support 32 bit time.  It is done through a new build flags,
_TIME_BITS=64, which is supported only when Long File Support is also
used (_FILE_OFFSET_BITS=64).  The new flag redefine the required
structures and redirected the required symbols to newer exported ones.

However, different then LFS support, the new 64 bit time_t symbols
are only exported for the ABI that require them.  ABIs that provides
64 bit time as the default ABI are unaffected.

On Linux, to fully support 64 bit time_t it requires a minimum of
kernel v5.1 due the newer syscalls.

I checked for i686-linux-gnu running on a x86_64 5.4 kernel,
powerpc-linux-gnu running on ppc64 5.10 kernel, and on
arm-linux-gnueabihf running on arm64 5.4 kernel.  The new 64 bit time_t
tests when running on older kernels shows as unsupported.
