[svn-r10652] Purpose: Update config for AIX

Description:
    Many warnings about duplicate symbols for various members in the std.

Solution:
    Temporarily added -qweaksymbol to suppress linker messages warning
    of duplicate symbols since these warnings are harmless.

    Note from pSeries and AIX Information Center:
        When compiling C++ programs containing extern inline functions,
        you can use the -qweaksymbol compiler option to suppress linker
        messages warning of duplicate symbols.

    Hoping that a better solution is suggested or the problem will be
    handled by the compiler in the future.

Platforms tested:
    AIX 5.1 (copper)
