- Update to glibc 2.35
Major new features:
* Unicode 14.0.0 Support
* Bump r_version in the debugger interface to 2
* Support for the C.UTF-8 locale has been added to glibc
* <math.h> functions that round their results to a narrower type, and
corresponding <tgmath.h> macros, are added from TS 18661-1:2014, TS
18661-3:2015 and draft ISO C2X
* <math.h> functions for floating-point maximum and minimum,
corresponding to new operations in IEEE 754-2019, and corresponding
<tgmath.h> macros, are added from draft ISO C2X
* <math.h> macros for single-precision float constants are added as a
GNU extension
* The __STDC_IEC_60559_BFP__ and __STDC_IEC_60559_COMPLEX__ macros are
predefined as specified in TS 18661-1:2014
* The exp10 functions in <math.h> now have a corresponding type-generic
macro in <tgmath.h>
* The ISO C2X macro _PRINTF_NAN_LEN_MAX has been added to <stdio.h>
* printf-family functions now support the %b format for output of
integers in binary, as specified in draft ISO C2X, and the %B variant
of that format recommended by draft ISO C2X
* A new DSO sorting algorithm has been added in the dynamic linker that uses
topological sorting by depth-first search (DFS), solving performance issues
of the existing sorting algorithm when encountering particular circular
object dependency cases
* A new tunable, glibc.rtld.dynamic_sort, can be used to select between
the two DSO sorting algorithms
* ABI support for a new function '__memcmpeq'. '__memcmpeq' is meant
to be used by compilers for optimizing usage of 'memcmp' when its
return value is only used for its boolean status

- Add ExtraBuildFlags for build flags that cannot be passed to configure.
------------------( below changes from previous sr )---------------------------
- Pass livepatchable flags directly to make.
- Add optional support for livepatches (JSC #SLE-20049).
- Generate ipa-clones tarball artifact when livepatch support is enabled.
Userspace Livepatching allows your application to be updated without restarting. For a library to be livepatchable, it has to be compiled with special flags (-fpatchable-functions-entry=X,Y).
To aid the development of livepatches, ipa-clones are also generated in the build process and packed into a livepatch-devel package. This package is meant to be used by developers during their workflow: these files contains log of changes that gcc did in the compiled code that may change code layout, which must be accounted when developing a livepatch. For instance, livepatching a function which is inlined requires livepatching every function that calls it. Tools that use such files already exists in kernel-livepatching and we aim porting them to userspace livepatching as well.

from subdirectories under the glibc-hwcaps directory on the library
search path if the system's capabilities meet the requirements for
that subdirectory.
* The new --help option of the dynamic linker provides usage and
information and library search path diagnostics.

but with larger field widths to accurately report values that are
larger than fit in an integer.

* A new fortification level _FORTIFY_SOURCE=3 is available.
* The mallinfo function is marked deprecated.

implementations from HWCAP subdirectories are no longer loaded.
* The deprecated <sys/vtimes.h> header and the function vtimes have been
removed.
* On s390(x), the type float_t is now derived from the macro
__FLT_EVAL_METHOD__ that is defined by the compiler, instead of being
hardcoded to double.
* A future version of glibc will stop loading shared objects from the
"tls" subdirectories on the library search path, the subdirectory that
corresponds to the AT_PLATFORM system name, and also stop employing
the legacy AT_HWCAP search mechanism.
* CVE-2021-3326: An assertion failure during conversion from the
ISO-20220-JP-3 character set using the iconv function has been fixed.
