guix: combine and document enable_werror

Browse source 
Combine into hardened-glibc.
Document why we don't use --disable-werror directly.

https://www.gnu.org/software/libc/manual/html_node/Configuring-and-compiling.html
> By default, the GNU C Library is built with -Werror. If you wish
> to build without this option (for example, if building with a
> newer version of GCC than this version of the GNU C Library was
> tested with, so new warnings cause the build with -Werror to fail),
> you can configure with --disable-werror.
