The patch adds redirections for xclock_gettime, xclock_settime,
timespec_add, timespec_sub, test_timespec_before_impl,
test_timespec_equal_or_after_impl, support_timespec_ns,
support_timespec_normalize, and support_timespec_check_in_range when
_TIME_BITS=64 is defined.

I used these shell commands:
../glibc/scripts/update-copyrights $PWD/../gnulib/build-aux/update-copyright
(cd ../glibc && git commit -am"[this commit message]")
and then ignored the output, which consisted lines saying "FOO: warning:
copyright statement not found" for each of 6694 files FOO.
I then removed trailing white space from benchtests/bench-pthread-locks.c
and iconvdata/tst-iconv-big5-hkscs-to-2ucs4.c, to work around this
diagnostic from Savannah:
remote: *** pre-commit check failed ...
remote: *** error: lines with trailing whitespace found
remote: error: hook declined to update refs/heads/master

Fix time/tst-cpuclock1 intermitent failures
has 2 issues:
1. It assumes time_t == long which is false on x32.
2. tst-timespec.c is compiled without -fexcess-precision=standard which
generates incorrect results on i686 in support_timespec_check_in_range:
double ratio = (double)observed_norm / expected_norm;
return (lower_bound <= ratio && ratio <= upper_bound);
This patch does
1. Compile tst-timespec.c with -fexcess-precision=standard.
2. Replace long with time_t.
3. Replace LONG_MIN and LONG_MAX with TYPE_MINIMUM (time_t) and
TYPE_MAXIMUM (time_t).
This test fails intermittently in systems with heavy load as
CLOCK_PROCESS_CPUTIME_ID is subject to scheduler pressure. Thus the
test boundaries were relaxed to keep it from failing on such systems.
A refactor of the spent time checking was made with some support
functions. With the advantage to representing time jitter in percent
of the target.
The values used by the test boundaries are all empirical.

It adds useful functions for tests that use struct timespec.
Checked on x86_64-linux-gnu and i686-linux-gnu.
* support/timespec.h: New file. Provide timespec helper functions
along with macros in the style of those in check.h.
* support/timespec.c: New file. Implement check functions declared
in support/timespec.h.
* support/timespec-add.c: New file from gnulib containing
timespec_add implementation that handles overflow.
* support/timespec-sub.c: New file from gnulib containing
timespec_sub implementation that handles overflow.
* support/README: Mention timespec.h.
