Official s390x support

Hi,

I installed a Qiskit 0.30 env on an IBM LInuxONE machine and want to utilize kaleidoscope to get a good presentation.
The installation of kaleidoscope is successful, but when i attempting to run the sample test code, i immediately get the "Segmentation fault (core dumped)" error, see below.

The maintainer of kaleidoscope confirmed that the issue located somewhere in llvmlite.
issue link: https://github.com/QuSTaR/kaleidoscope/issues/63

Can someone help on this?

Thanks!

Reproduce the import failure on the IBM LinuxONE s390x environment described in the issue, using the sample imports and Python fault-handler trace. Start with the llvmlite/binding/ffi.py load path and the linked kaleidoscope report; done means the supported s390x setup can import the relevant packages without a segmentation fault.
