     Add a -rpath entry for the RTS library, so that it can find libffi

     This fixes dynamic library resolution when --enable-new-dtags is used
     (#7062).

     When --enable-new-dtags is used when linking an executable, a RUNPATH
 as
     well as RPATH is set. The linker then ignores RPATH, and RUNPATH is
 only
     used for directly (not transitively) needed libraries. As the program
     doesn't directly need libffi, it isn't found.
