Re: [PATCH] string: Declare Issue 8 functions for POSIX.1-2024 [BZ #34466]

For the record, on the Linaro TCWG precommit result for this patch
(1 regression, 97 fixes on aarch64): the one regression,
nptl/tst-sem_getvalue-affinity, is a CI-environment timeout, not
something this patch can influence.  Its log shows the affinity test
being killed at its own timeout after skipping several CPU set sizes,
and sibling affinity tests report UNSUPPORTED because the container
cannot create cgroupv2 groups.  The patch only adds declarations under
__USE_XOPEN2K24 plus new tests; the 97 fixes are the existing conform
and header tests that now see the POSIX.1-2024 declarations.
