It all works - wheels for AIX - up to a point

Spent some hours - experimenting...

So - short story - it works. There remains a big chance for failure
though as the current tag ignores differences in TL level, build_date,
etc.. Also, a source for failure, is no recognition for 32-bit or 64-bit.


However, focusing on the good news - the wheels install - without a
compiler being called.

Looking Forward!!
AIX has a long history of letting binaries from the past be reused: See:
https://www.ibm.com/support/knowledgecenter/ssw_aix_72/install/binary_compatability.html

++++++ The gritty details, for the curious/interested

After having used devpi (client) to upload to a test devpi-server I
pointed my pip at the devpi-server to download the packages.

Note: using default pipy "source" I would get two .gz files.

The initial upload is from an AIX 6.1 server, the download here is to an
AIX 7.1 server.

So, a wheel (for pycparser) and a .gz (for cffi).

Phase 2:

repeat the upload of cffi, but now from an AIX 7.1 server.
