ppc logs every type of Invalid instruction. This generates a lot
of garbage on console when sshd/ssh_keygen executes as
they try various insn to optimize its performance.
The invalid operation log is still there so an unknown insn
will still be logged.

QEMU can autodetect if it is started from Linux binfmt loader
when binfmt flag O is on.
Use that and require binfmt flag P as well which will enable QEMU
to pass in correct argv0 to the application.
