I don't know Arch, but Debian does it by applying a patch:

https://sources.debian.org/src/bash/5.1-2/debian/patches/deb-bash-config.diff/

The last piece of that patch sets the SSH_SOURCE_BASHRC macro in the
config-top.h file, which is what enables the feature.  I would guess
that Arch does something similar, with whatever system of source code
patches it uses.
