I still get the libs that I don't want. To ensure I did what you
asked:
$ /bin/sh ../../../libtool --tag=CC --mode=compile icpc -DHAVE_CONFIG_H -I. -I../../../opal/include -I../../../orte/include -I../../../ompi/include -I../../../opal/mca/paffinity/linux/plpa/src/libplpa -DOMPI_BUILDING_CXX_BINDINGS_LIBRARY=1 -DOMPI_SKIP_MPICXX=1 -I../../.. -O3 -DNDEBUG -Wall -static-intel -m64 -finline-functions -fexceptions -pthread -MT comm.lo -MD -MP -MF \$depbase.Tpo -c -o comm.lo comm.cc
