Hmm. I see the corresponding MR [1] mentions that this was made with a
straightforward sed invocation from the riscv64 config.  I'd very much
prefer to incorporate results from real native builds.

How do you know if the resulting binaries work at all?

I can see that architecture bootstrapping needs something like this for
starters, though I wonder why not mips64el as I understand it's more
similar hardware. But that seems like something you could/should do
in a private repository to get a working build environment together,
and then do native builds with that.

Also it looks like not even dpkg has loongarch64 support yet so this
seems rather early.
