forked from pool/glibc

- Update to glibc 2.34
Major new features:
* When _DYNAMIC_STACK_SIZE_SOURCE or _GNU_SOURCE are defined,
PTHREAD_STACK_MIN is no longer constant and is redefined to
sysconf(_SC_THREAD_STACK_MIN)
* Add _SC_MINSIGSTKSZ and _SC_SIGSTKSZ
* The dynamic linker implements the --list-diagnostics option, printing
a dump of information related to IFUNC resolver operation and
glibc-hwcaps subdirectory selection
* On Linux, the function execveat has been added
* The ISO C2X function timespec_getres has been added
* The feature test macro __STDC_WANT_IEC_60559_EXT__, from draft ISO
C2X, is supported to enable declarations of functions defined in Annex F
of C2X
* Add support for 64-bit time_t on configurations like x86 where time_t
is traditionally 32-bit
* The main gconv-modules file in glibc now contains only a small set of
essential converter modules and the rest have been moved into a supplementary
configuration file gconv-modules-extra.conf in the gconv-modules.d directory
in the same GCONV_PATH
* On Linux, a new tunable, glibc.pthread.stack_cache_size, can be used
to configure the size of the thread stack cache
* The function _Fork has been added as an async-signal-safe fork replacement
since Austin Group issue 62 droped the async-signal-safe requirement for
fork (and it will be included in the future POSIX standard)
* On Linux, the close_range function has been added
* The function closefrom has been added
* The posix_spawn_file_actions_closefrom_np function has been added, enabling
posix_spawn and posix_spawnp to close all file descriptors great than or
equal to a giver integer
