It looks like that gives us the link line we want, yet we still get the
libimf.so dependency:

$ /bin/sh ../../../libtool --tag=CC   --mode=link icpc  -O3 -DNDEBUG -Wall 
-static-intel -m64 -finline-functions -fexceptions -pthread -version-info 0:0:0 
-export-dynamic  -fexceptions  -o libmpi_cxx.la -rpath
