- Update to glibc 2.33
  * The dynamic linker accepts the --list-tunables argument which prints
    all the supported tunables.
  * The dynamic linker accepts the --argv0 argument and provides opportunity
    to change argv[0] string.
  * The dynamic linker loads optimized implementations of shared objects
    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.
  * The mallinfo2 function is added to report statistics as per mallinfo,
    but with larger field widths to accurately report values that are
    larger than fit in an integer.
  * Add <sys/platform/x86.h> to provide query macros for x86 CPU features.
  * A new fortification level _FORTIFY_SOURCE=3 is available.
  * The mallinfo function is marked deprecated.
  * When dlopen is used in statically linked programs, alternative library
    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. (forwarded request 868599 from Andreas_Schwab)
