guix: enable hardening options in GCC Build
Pass `--enable-default-pie` and `--enable-default-ssp` when configuring
our GCCs. This achieves the following:
--enable-default-pie
Turn on -fPIE and -pie by default.
--enable-default-ssp
Turn on -fstack-protector-strong by default.
Note that this isn't a replacement for passing hardneing flags
ourselves, but introduces some redundency, and there isn't really a
reason to not build a more "hardenings enabled" toolchain by default.
