qemu-sbruno has multiple build failures if QEMU_USER_STATIC is set in make.conf. first, the post-install step fails because two binaries aren't present. That can easily be fixed with the attached patch.
Secondly, even with the attached patch, there are plist discrepancies regarding non-amd64 targets. These discrepancies persist even if X86_TARGETS=off. I haven't found a solution for that. Instead, I created a new port to satisfy my needs: emulators/qemu-utils. I'll attach a poudriere log showing these plist errors too.
