I haven't had the time to do it yet, however, it seems OTP 20 has
simply applied the patch I mentioned:
https://github.com/erlang/otp/pull/1394/commits/024e438101c010f17e3a374117c3b376d48483f3

If I understand correctly this configure, there is a test in the
configure to automatically enable HiPE for a list of architectures.
ppc64 is present in this list but not ppc64le. So, I think HiPE would
be disabled on ppc64le architectures even if we bump to OTP 20.

Best,
