[PATCH] NEWS: Add entry for glibc-hwcaps and deprecate legacy hwcaps

[Paul Zimmermann]

       Dear Florian,

> +* 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.  Initially supported subdirectories include
> +  "power9" and "power10" for the powerpc64le-linux-gnu architecture,
> +  "z13", "z14", "z15" for s390x-linux-gnu, and "x86-64-v2", "x86-64-v3",
> +  "x86-64-v4" for x86_64-linux-gnu.  In the x86_64-linux-gnu case, the
> +  subsdirectory names correspond to the vendor-independent x86-64

subsdirectory -> subdirectory
