[svn-r17643] Purpose:

    Configure / Config File Fixes

Description:

    1. Made AM_CPPFLAGS assignments in configure a bit safer. (i.e., check to
       ensure include paths exist before adding them to AM_CPPFLAGS).

    2. Change AIX config file to add -D_LARGE_FILES into AM_CXXFLAGS instead
       of H5_CXXFLAGS (same with *_CFLAGS). This will propagate it into 
       h5c++, where it is needed to compile correctly.

    3. Added missing line containing AM_CFLAGS to configure output summary.

Tested:

    h5committest, and uP (AIX machine, via Albert).
