hardened profile specs: default vanilla
non-hardened profile specs: hardened default
basically, while building gcc, we do something like:
if use hardened ; then
cp hardened.specs specs
else
cp vanilla.specs specs
fi
where "specs" represents the default compiler settings
so the `gcc-config -l` output on a hardened system lists "vanilla" as an
option while on a non-hardened system you get the option "hardened"

see above as to why your diff showed no differences
