That's (emulated) native compilation (which requires setting up QEMU 
transparent emulation), not cross-compilation.  While they can 
accomplish the same result, they function completely different -- from 
Guix POV, emulated builds are just native (non-cross-compiling) builds.

Instead, try

./pre-inst-env guix build --target=aarch64-linux-gnu go-ipfs

... which will fail because the imported-modules aren't imported, which 
is a bug (I'll report it).
