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].

-//==============================================================
-// 05/31/01 Initial version
-// 05/20/02 Cleaned up namespace and sf0 syntax
-// 02/10/03 Reordered header: .section, .global, .proc, .align
-//
-// API
-//==============================================================
-// float fmaxf  (float x, float y)
-//
-// Overview of operation
-//==============================================================
-// returns the algebraic maximum of 2 input values
-//
-// Special cases:
-//    fmaxf(x, nan) returns x if x is numeric  // Must special case this one
-//    fmaxf(nan, y) returns y if y is numeric
-//    fmaxf(nan1, nan2) returns quietized nan2
-//    fmaxf(+0,+0) returns +0
-//    fmaxf(-0,+0) returns +0
-//    fmaxf(-0,-0) returns -0
-//    fmaxf(+0,-0) returns +0                  // Must special case this one
-//
-// SNaN causes invalid to be set
-
-// floating-point registers used: 2
-// f8,  input x, output
-// f9,  input y
