Oops! I neglected to say that you can effect this behavior by
specifying the "--disable-dlopen" flag to OMPI's configure. This
turns off our internal libltdl entirely (i.e., it doesn't even build)
and simultaneously slurps all of our plugins up into their relevant
libraries (e.g., libmpi.so, libopen-pal.so, etc.).
