FYI: qemu-ppc64-static and qemu-ppc-static "live-hang" when I attempt use with poudriere; qemu-arm-static and qemu-aarch64-static work

qemu-ppc64-static and qemu-ppc-static "live-hang" when I
attempt use them with poudriere, hanging at the command
(showing an example process id):

/usr/local/bin/qemu-ppc-static /bin/ps -ww -p 47841 -o jid=

which eats CPU time and grows memory SIZE over time.
Examples from after waiting a while in each case:

  PID USERNAME    THR PRI NICE   SIZE    RES   SWAP STATE   C   TIME     CPU COMMAND
48319 root          2 103    0  8413M   234M     0K CPU11  11   2:50 101.97% /usr/local/bin/qemu-ppc64-static /bin/ps -ww -p 48318 -o jid

  PID USERNAME    THR PRI NICE   SIZE    RES   SWAP STATE   C   TIME     CPU COMMAND
47842 root          2 103    0 16597M   455M     0K CPU1    1   5:25  96.38% /usr/local/bin/qemu-ppc-static /bin/ps -ww -p 47841 -o jid=


By contrast I've no such problem with qemu-arm-static or
qemu-aarch64-static : these were able to build lang/gcc7
(full bootstrap) in between 4 and 5 hours hours each,
the prerequisites also being built in the process.

My attempts to manually use qemu-ppc64-static and qemu-ppc-static
(with -L supplied) also get such results. The same for
qemu-ppc*-static running a statically linked rescue program (so
no -L needed).

It appears that qemu-ppc64-static and qemu-ppc-static from
emulators/qemu-user-static are broken.
