Bug#1103803: onednn FTCBFS for arm64 on amd64: build vs host confusion
Source: onednn
Version: 3.7.2+ds-1
Tags: patch
User: debian-cross@lists.debian.org
Usertags: ftcbfs
onednnn fails to cross build from source for arm64 on amd64, because it
confuses build and host architecture and thus gets architecture-specific
parameters wrong. I'm attaching a patch to fix that.
