Remove ia64-linux-gnu

Linux 6.7 removed ia64 from the official tree [1], following the general
principle that a glibc port needs upstream support for the architecture
in all the components it depends on (binutils, GCC, and the Linux
kernel).

Apart from the removal of sysdeps/ia64 and sysdeps/unix/sysv/linux/ia64,
there are updates to various comments referencing ia64 for which removal
of those references seemed appropriate. The configuration is removed
from README and build-many-glibcs.py.

The CONTRIBUTED-BY, elf/elf.h, manual/contrib.texi (the porting
mention), *.po files, config.guess, and longlong.h are not changed.

For Linux it allows cleanup some clone2 support on multiple files.

The following bug can be closed as WONTFIX: BZ 22634 [2], BZ 14250 [3],
BZ 21634 [4], BZ 10163 [5], BZ 16401 [6], and BZ 11585 [7].

-  Notes on how to update libm based on Intel's libm releases
-  ----------------------------------------------------------
-
-This source code in this directory is currently based on Intel libm
-v2.1 as available from:
-
-  http://www.intel.com/software/products/opensource/libraries/num.htm
-
-To ease importing, fix some bugs, and simplify integration into libc,
-it is also necessary to apply the patch at:
-
-  ftp://ftp.hpl.hp.com/pub/linux-ia64/intel-libm-041228.diff.gz
-
-The expectation is that Intel will integrate most if not all of these
-changes into future releases of libm, so this patching step can
-hopefully be omitted in the future.
-
-Once the patched libm sources are extracted in a directory $LIBM, they
-can be imported into the libc source tree at $LIBC with the following
-step:
-
-	$ cd $LIBC/src/sysdep/ia64/fpu
-	$ ./import_intel_libm $LIBM
-
-This should produce a number of "Importing..." messages, without
-showing any errors.
-
-At this point, you should be able to build glibc in the usual fashion.
-We assume you do this in directory $OBJ.  Once the build has
-completed, run "make check" to verify that all (math) checks succeed.
-If these checks succeed, you should also run the following commands to
-verify that the new libm doesn't pollute the name-space and has proper
-size-info for the data objects:
-
-	$ cd $LIBC/src/sysdep/ia64/fpu
-	$ import_check $OBJ/math/
-
-There should be no (unexpected) errors reported by this script.
-
-As an optional step, you may also want to confirm that the new libm
-exports the exact same global symbols as the old one.
-
-If you want to see the changes introduced by the "import_intel_libm"
-script, you can run the commands:
-
-	$ cd $LIBC/src/sysdep/ia64/fpu
-	$ import_diffs
-
-That's it.
