Linking against slepc doesn't encode correct link path

Bug Description

I have a system installed slepc (3.2) linked against a system installed petsc (3.2). However, I use my own version of petsc 3.3 and corresponding slepc. Although the libadjoint Makefile correctly obeys my SLEPC_DIR setting at compile and link time, at runtime, the library picks up the system installed slepc instead (although the user-installed petsc). This leads to all sorts of horrible problems. I think the Makefile should encode the library search path into libadjoint at runtime (as is done for the petsc link).

Perhaps something like this (this is almost certainly not the correct voodoo for macos):
