That makes sense, but I'm not using it. So presumably I've added a configure option that I didn't need (either "--host=x86_64-my-linux" or "--build=x86_64").

I'm building against a Yocto SDK (like described at https://www.yoctoproject.org/docs/2.1/sdk-manual/sdk-manual.html#sdk-installing-the-sdk), and the --host option identifies the sysroot.

When I add just --host, I also have to add --build, and IIRC only x86_64 worked. Could that have enabled the multiarch settings? Or it is always enabled because I'm building on an Ubuntu VM?
