Converts qemu x86 machines to boot using distro_config. The intent is to allow u-boot in qemu to be maximally compatible with many boot methods without having to change the config. Previously, u-boot would only boot in a very limited set of circumstances where there was a /boot/vmlinuz on scsi 0:3 with no ramdisk.
