SIGILL is probably due to in-core AES crypto instruction from POWER8
and above. It sounds like the call to rijndael_encryptCBC is _not_
being guarded with a runtime check. Instead of falling back to a
software-only implementation, it sounds like POWER8 AES instructions
are being used unconditionally.

In the past, the problem was due to building the package with
-mcpu=power8 or similar. It happens to a lot of packages.
