Fix port to 32-bit AIX.

* configure.ac (opsys): On Power Architecture, treat release 7 of
AIX like releases 5 and 6.
* src/unexaix.c (copy_text_and_data): Don't add text_scnptr to ptr
twice.  _text already includes this offset.
(unrelocate_symbols): Don't cast 64-bit integer to pointer.

Fixes: debbugs:17540
