It would be nice to have a --static-user config flag and deprecate the
--static flag. I don't think there is a decent use case for system
emulation targets.

The Gentoo ebuild currently jumps through hoops to build QEMU by doing
the build twice, first for softmmu targets and then for user targets. I
suspect all of that is mostly to handle the reasonable "static-user" use
case which is what people really want*.
