Problem compiling krb5 1.17 under AIX 7.2.

Dear Group,
I could now compile, link and build the sources flawlessly with the help of
an old thread which I found in your mailing list:
https://www.mail-archive.com/kerberos@mit.edu/msg12688.html
What I did wrong was to create archive files of the .so files instead of
linking them and then using the -brtl flag (all explained in the link
above).
Also here is a blog post which helped me in the overall process:

Best,
Oliver
