[svn-r17663] Purpose:

    configure cleanup

Description

    1. Removed check that disables shared libraries when pgcc is used. Apparently
       they previously did not work with libtool 1.5.14 and on mir, neither of
       which is in use anymore. Testing on jam and amani appear fine, so this
       check is unnecessary.

    2. Removed check that disables shared C++ libraries when -xarch is used to
       enable 64 bit mode. We now use m64 flag to build 64 bit binaries, so 
       we shouldn't explicitly disable shared C++ libraries if -xarch is 
       discovered.

    3. Removed old configure output summary section from configure.in, since
       we now use the libhdf5.settings file.

    4. Updated powerpc-ibm-aix5.x config file to once again put c99 flag into
       H5_CFLAGS (and thus NOT get into h5cc), as decided in our dev meeting.

Tested:

    h5committest
    full build with pgcc on jam / amani
