Make builds with VT default to using stlport4 when compile with Oracle Studio compilers

[ompiteam]

When building OMPI with Oracle Studio C++ compilers and having VT configured on one will be met with the following messages

WARNING: **************************************************************

WARNING: *** Please try again re-configuring Open MPI with using

It would be nice if configure detected this case and automatically add -library=stlport4 to CXXFLAGS.
