[Qemu-ppc] Configure Qemu-PPC for i386 target?

[Jd Lyons]

What it the proper way to configure Qemu to make i386 target binaries?

I’ve made some code changes to Qemu, and it builds, but I’m getting undefined symbols when it tries to link:

LINK    ppc64-softmmu/qemu-system-ppc64

Undefined symbols for architecture x86_64:

I’m not sure if it’s an issue where I need to build my code changes to be i386, but I’m trying to pin down the problem.
