You'll also need to set this in mpicxx.

This is generated during the configure step at the same time as the
other mpi* compiler scripts.  It looks like you're having to take this
additional step because of some tests during configure that will not use
-R over -Wl,-rpath-link -Wl, unless the arch is detected as solaris.

We'll look into a more direct solution for users of Sun Studio in future
releases.
