Some distributions ban the /usr/bin/python path in their build
systems due to the ambiguity of whether it refers to Python 2 or
Python 3. Python 2 has been out of support for many years, and
glibc has required Python 3 at build time for a while. So it seems
safe to switch the remaining scripts over to /usr/bin/python3.

The recent commit 638d437dbf9c68e40986edaa9b0d1c2e72a1ae81
"Deprecate s390-linux-gnu (31bit)"
leads to:

The build is fixed by explicitely disabling multilib.

The support for lock elision was already deprecated with glibc 2.42:
commit 77438db8cfa6ee66b3906230156bdae11c49a195
"Mark support for lock elision as deprecated."
See also discussions:
https://sourceware.org/pipermail/libc-alpha/2025-July/168492.html
This patch removes the architecture specific support for lock elision
for x86, powerpc and s390 by removing the elision-conf.h, elision-conf.c,
elision-lock.c, elision-timed.c, elision-unlock.c, elide.h, htm.h/hle.h files.
Those generic files are also removed.
The architecture specific structures are adjusted and the elision fields are
marked as unused. See struct_mutex.h files.
Furthermore in struct_rwlock.h, the leftover __rwelision was also removed.
Those were originally removed with commit 0377a7fde6dfcc078dda29a1225d7720a0931357
"nptl: Remove rwlock elision definitions"
and by chance reintroduced with commit 7df8af43ad1cd8ce527444de50bee6f35eebe071
"nptl: Add struct_rwlock.h"
The common code (e.g. the pthread_mutex-files) are changed back to the time
before lock elision was introduced with the x86-support:
- commit 1cdbe579482c07e9f4bb3baa4864da2d3e7eb837
"Add the low level infrastructure for pthreads lock elision with TSX"
- commit b023e4ca99f5e81f90d87d23cd267ef2abd2388c
"Add new internal mutex type flags for elision."
- commit 68cc29355f3334c7ad18f648ff9a6383a0916d23
"Add minimal test suite changes for elision enabled kernels"
- commit e8c659d74e011346785355eeef03b7fb6f533c61
"Add elision to pthread_mutex_{try,timed,un}lock"
- commit 49186d21ef2d87986bccaf0a7c45c48c91b265f3
"Disable elision for any pthread_mutexattr_settype call"
- commit 1717da59aed9612becd56aaa1249aac695af4c8a
"Add a configure option to enable lock elision and disable by default"
Elision is removed also from the tunables, the initialization part, the
pretty-printers and the manual.
Some extra handling in the testsuite is removed as well as the full tst-mutex10
testcase, which tested a race while enabling lock elision.
I've also searched the code for "elision", "elide", "transaction" and e.g.
cleaned some comments.
I've run the testsuite on x86_64 and s390x and run the build-many-glibcs.py
script.
Thanks to Sachin Monga, this patch is also tested on powerpc.
A NEWS entry also mentions the removal.

This patch adds new flag --glibctunables to the cross-test-ssh.sh script
to pass Glibc tunables to the system on which tests are executed.
The value to pass can be also provided via the GLIBC_TUNABLES environment
variable.
This works similar to the TIMEOUTFACTOR variable.
Sometimes it is useful to cross test glibc with some non-default tunable,
and a global environment variable is the easiest way to inject some
tunable value into most tests. With this patch using cross-test-ssh.sh
script becomes very similar to running a test natively on the local host
when using non-default tunable is important.

For each input readelf output, localplt.awk parses each 'Relocation
section' entry, checks its offset against the dynamic section entry, and
saves each DT_JMPREL, DT_RELA, and DT_REL offset value it finds. After
all lines are read, the script checks if any segment offset differed
from 0, meaning at least one 'Relocation section' was matched.
However, if the shared object was built with RELR support and the static
linker could place all the relocation on DT_RELR, there would be no
DT_JMPREL, DT_RELA, and DT_REL entries; only a DT_RELR.
For the current three ABIs that support (aarch64, x86, and powerpc64),
the powerpc64 ld.so shows the behavior above. Both x86_64 and aarch64
show extra relocations on '.rela.dyn', which makes the script check to
succeed.
This patch fixes by handling DT_RELR, where the offset is checked
against the dynamic section entries and if the shared object contains an
entry it means that there are no extra PLT entries (since all
relocations are relative).
It fixes the elf/check-localplt failure on powerpc.
Checked with a build/check for aarch64-linux-gnu, x86_64-linux-gnu,
i686-linux-gnu, arm-linux-gnueabihf, s390x-linux-gnu, powerpc-linux-gnu,

Sort tunables list at the time it's generated. Note: adding new
tunables will cause other tunable IDs to change, but that was
the case before anyway. POSIX does not guarantee the order of "foo
in bar" AWK operators, so the order was indeterminate before anyway.
Even depending on the order to be the same across multiple calls,
such as in this script, is undefined, so sorting the list resolves
that also.
Note that sorting is not dependent on the user's locale.
