python27 fails to install on aix 6.1 for 2015Q4

[J Raynor <jxraynor%gmail.com@localhost>]

python27 built successfully on aix 6.1, but the installation failed
during package creation.  I've included the tail end of the output at
the bottom of this email, but the problem is that, for aix, only
libpython2.7.so gets built, and not also libpython2.7.so.1.0.  PLIST
is expecting both, even though some systems will only build the
former.

I've attached a patch that fixes the problem by adding a PLIST_VAR to
cover the optional installation of the .so.1.0 file.
