Subject: [svn-r7047] Purpose: Improvement

Description:
If $CXX is not defined, configure will try a list of possible
C++ compiler name.  That is not always desireable.

Solution:
Change configure to combine all powerpc-ibm-aix* to one version.
Add xlC as the default $CXX value.

Platforms tested:
Tested in Copper only since the change affect AIX machine only.

Misc. update:
