The Linux version already target the current thread by using tgkill
along with getpid and gettid.
For arm, libpthread does not do a intra PLT since it will call the
raise from libc.

The libpthread compat symbol requires to mask it when building the

The libc version is identical and built with same flags. Both aarch64
and nios2 also requires to export __send and tt was done previously with
the HAVE_INTERNAL_SEND_SYMBOL (which forced the symbol creation).
All __send callers are internal to libc and the original issue that
required the symbol export was due a missing libc_hidden_def. So
a compat symbol is added for __send and the libc_hidden_def is
defined regardless.

This change adds new test to assess sigtimedwait's timeout related
functionality - the sigset_t is configured for SIGUSR1, which will
not be triggered, so sigtimedwait just waits for timeout.
To be more specific - two use cases are checked:
- if sigtimedwait times out immediately when passed struct timespec has
zero values of tv_nsec and tv_sec.
- if sigtimedwait times out after timeout specified in passed argument

After this patch applied the ntp_gettimex function is always declared
in the sys/timex.h header. Currently it is not when __REDIRECT_NTH is
defined (i.e. in ARM 32 bit port).

Some Linux filesystems might not fully support 64 bit timestamps [1],
which make some Linux specific tests to fail when they check for the
functionality.
This patch adds a new libsupport function, support_path_support_time64,
that returns whether the target file supports or not 64 bit timestamps.
The support is checked by issuing a utimensat and verifying both the
last access and last modification time against a statx call.
The tests that might fail are also adjusted to check the file support
as well:

Now that fstat is implemented on top fstatat we need to handle negative
inputs. The implementation now rejects AT_FDCWD, which would otherwise
be accepted by the kernel.

This patch updates the kernel version in the test tst-mman-consts.py
to 5.11. (There are no new MAP_* constants covered by this test in
5.11 that need any other header changes.)
Tested with build-many-glibcs.py.

Now that compat_symbol_reference works in non-internal tests.
Also do not build and run the test at all on architectures which

compat_symbol_reference works in non-internal tests now. Also
avoid building the test for unsupported configurations at all.
I verified by building with build-many-glibcs.py that GLIBC_2.1.3
works as the predecessor of GLIBC_2.2. (Symbol versions in
the early days are complex.)

This code privides test to check if time on target machine is properly
adjusted.
The time is altered only when cross-test-ssh.sh is executed with
--allow-time-setting flag.
As the delta added to CLOCK_REALTIME is only 1 sec the original time is
not restored and further tests are executed with this bias.

There were following problems discovered for tst-timerfd test:
1. Do not set the struct itimerspec's it_interval tv_sec to 2 seconds.
After this change the timerfd will trigger only once (the it_value is
only set in this case).
2. The 'val1' variable (including the call to timerfd_gettime) is not
needed anymore, as it is just enough to read the struct itimerspec
after sleep. As a consequence the 'val2' has been renamed to 'val'.
3. After calling timerfd_gettime, the value of struct itimerspec time,
when timer is running, is the remaining time. In the case of this test
it would be less than 1 second.
As a result the TEST_COMPARE macro logic had to be adjusted.

This patch provides test for utimes. It uses wrapper to read
access and modification times to compare them with ones written by
utimes.
Moreover, access and modification times beyond the Y2038 threshold
date (i.e. 32 bit time_t overflow) are also checked.
