- Update to glibc 2.32
  * Unicode 13.0.0 Support
  * New locale added: ckb_IQ
  * The GNU C Library now loads audit modules listed in the DT_AUDIT and
    DT_DEPAUDIT dynamic section entries of the main executable
  * powerpc64le supports IEEE128 long double libm/libc redirects when
    using the -mabi=ieeelongdouble to compile C code on supported GCC
    toolchains
  * To help detect buffer overflows and other out-of-bounds accesses
    several APIs have been annotated with GCC 'access' attribute
  * On Linux, functions the pthread_attr_setsigmask_np and
    pthread_attr_getsigmask_np have been added
  * The GNU C Library now provides the header file <sys/single_threaded.h>
    which declares the variable __libc_single_threaded
  * The functions sigabbrev_np and sigdescr_np have been added
  * The functions strerrorname_np and strerrordesc_np have been added
  * AArch64 now supports standard branch protection security hardening
    in glibc when it is built with a GCC that is configured with
    --enable-standard-branch-protection (or if -mbranch-protection=standard
    flag is passed when building both GCC target libraries and glibc,
    in either case a custom GCC is needed)
  * The deprecated <sys/sysctl.h> header and the sysctl function have been
    removed
  * The sstk function is no longer available to newly linked binaries
  * The legacy signal handling functions siginterrupt, sigpause, sighold,
    sigrelse, sigignore and sigset, and the sigmask macro have been
    deprecated
  * ldconfig now defaults to the new format for ld.so.cache
  * The deprecated arrays sys_siglist, _sys_siglist, and sys_sigabbrev
    are no longer available to newly linked binaries, and their declarations
