guix: Make it arch agnostic #21194
Description
It would be nice if guix was arch agnostic, so different archs can be used to get the same binary.
I tried running guix on amd64 and arm64, for the target bitcoin-62cc2180afc1-powerpc64le-linux-gnu.tar.gz and only got a few bits difference:
--- ./bitcoin-arm64/bin/bitcoin-cli
