maybe needs a runtime switch, too ... or is it ok to leave this
hard-coded to the x86_64 version?
Yes, it would have to switch based on the CPU's LM feature.
Anyway, I'd like to get some feedback on this idea here... What
do you think of the idea of getting rid of the qemu-system-i386
binary this way in the future?
I wonder if we should take this a step further and rename
qemu-system-x86_64 to qemu-system-x86! Distros can if they wish create
symlinks to both qemu-system-i386 and qemu-system-x86_64.
Then we would name the CPUs "foo-x86" and alias them to foo-x86_64 and,
if they don't have LM set, to foo-i386 as well.
