[PATCH] Final NEWS and README updates.

[Roland McGrath]

> +* Math library bug fixes. A thorough audit of all open math library bugs was

Two spaces between sentences.

> +* Timezone data is no longer installed. Timzone related binaries and scripts
> +  will continue to be installed.

Again here.  Also, typo: s/Timzone/Timezone/ and grammar/style:
"Timezone-related".

> -       x86_64-*-linux-gnu
> +       x86_64-*-linux-gnu      Includes x32 support

That can be read as it being x32 only.
Perhaps "Can build either x86_64 or x32" or something like that.


Thanks,
Roland
