It is scripts/qemu-binfmt-conf.sh script inside the qemu sources.
It was a fork of debian's d/update-binfmts.sh, updated for other
use cases.

You should not use upstream git of qemu, since it too lacks
important patches like this, - please don't suggest people
to use outdated sources.. :)

(just as a matter of fact, debian usually has new version of
qemu the next day it is released, and I usually keep it up
to date in backports. With debian stable and current qemu 5.
we have a bit of delay since there are a few other things to
backport, but we have 5.0 there).
