rev 49899 : 8202322: AIX: symbol visibility flags not support on xlc 12.1

 # Tell the compiler not to export any functions unless declared so in
 # the source code. On Windows, this is the default and cannot be changed.
 # On Mac, we have always exported all symbols, probably due to oversight
 # and/or misunderstanding. To emulate this, don't hide any symbols
 # by default.
+# On AIX/xlc we need at least xlc 13.1 for the symbol hiding
 # Also provide an override for non-conformant libraries.
