Looking at this, I wonder whether we really want the "-accel" option to
prioritize the accelerators in the order of appearance? A lot of other
CLI tools give the highest priority to the last parameter instead, e.g.
"gcc -O3 -O1" compiles with -O1, and not with -O3.
Also I think it might be quite common that there are shell scripts which
call "qemu-system-xxx -accel xyz $*" ... and if we don't invert the
priorities of -accel, it will be impossible to override -accel in that
case...
