I've seen problems like that (but not exactly the same) when there was a
stale kvm process running with the wrong architecture. Like:

https://trac.torproject.org/projects/tor/wiki/doc/TorBrowser/BuildingWithGitian#AssemblyErrorsinMismatchedArchitectureCode
https://trac.torproject.org/projects/tor/ticket/12391

Check if there are any qemu/kvm processes running, use run-on-target to
shut them down (or just kill them), and try the "make build" again.
