I think it would be a lot simpler to just add this to the 'standard'
gcc configure flags, in (gnu packages gcc), given that probably the
idea is to do this hardening for all packages?  Needs a world-rebuild
though.

Alternatively, the ssp and order hardening flags can be set in CFLAGS
for individual packages, maybe by default in 'gnu-build-system' and the
like.

Alternatively, you could look into how "--with-c-toolchain" does
things.

Greetings,
Maxime.
