[svn-r21997] Feature: HDFFV-7793: AIX Fortran and C++ Compiler version information

Added code to display the version information of XL fortran and C++ compiler
version information. (This is just a quick fix for the AIX XL compilers.
The overall algorithm of compilers version information needs an overhaul.)

Tested: ADA machine. (No committest because the changes applied to AIX XL
compilers only.)
