This happens:

Yes, this happened.

The source of that byte was:

https://wiki.freebsd.org/QemuUserModeHowTo

(now fixed). After fixing this:

/pou/jails/p64/rescue/ls 

works.

But:

/pou/jails/p64/usr/bin/id
Unable to load interpreter

Check foreign ABI support by running a static binary. If you see something
like the following then --magic or --mask argument (for ELF header) is wrong.

  $ /poudriere/jails/head-powerpc64/rescue/ls
  sh: /poudriere/jails/head-powerpc64/rescue/ls: Exec format error

but it may not help if dynamically linked binaries still fail

I want to test-build devel/jsoncpp, so...

This built a jail:

  poudriere jail -c -j p64 -a powerpc.powerpc64 -m svn+ssh -v head

But using it fails:

poudriere bulk -T -f ~/pkg/ppcone -j p64

qemu-user-static support for powerpc64 seems to be incomplete but
otherwise is supposed to work as follows. Only stuff represented on
pkg-fallout@ is known to work. aarch64 is also in a good shape but needs
devel/aarch64-binutils built with LDFLAGS+=-all-static copied inside jail.

freebsd-ppc@ folks may have a clue how to cross-build powerpc64 packages
without real hardware. If you're just looking for logs, see

Ah, one more thing: I added the binmiscctl environment for ppc64, as
described in

  https://wiki.freebsd.org/QemuUserModeHowTo

The problem is the correct name for binmiscctl and the correct 
for poudriere. That's what I'm missing.
