Subject: build: update to latest gnulib

build: update to latest gnulib

Pick up mbrto{c32,wc} optimizations on UTF-8 on GLIBC.
Note configure.ac defines the required GNULIB_WCHAR_SINGLE_LOCALE.
This speeds up wc -m by 2.6x, when processing non ASCII chars,
and will similarly speed up per character processing
in the impending cut multi-byte implementation.
* NEWS: Mention the wc -m speed improvement.

   'wc -l' now operates up to four and a half times faster on hosts that support
   Neon instructions.
 
+  'wc -m' now operates up to 2.6 times faster on GLIBC when processing
+  non-ASCII UTF-8 characters.

   'yes' now uses zero-copy I/O on Linux to significantly increase throughput.
   E.g., throughput improved 15x from 11.6GiB/s to 175GiB/s on a Power10 system.
