- 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 (forwarded request 951353 from Andreas_Schwab)
