My personal TODO list contains an item to add a 
        ./configure --with-system-qemu[=PATH]
build option which disables the qemu upstream build and instead uses the
existing distro provided qemu (default /usr/bin/$somethingTBD).

FWIW I would also like to add --disable-qemu-traditional at the same

Of course if someone was to beat me to it I'd be very pleased to review
a patch instead of writing it (especially given that autoconf is
involved ;-))
