[PATCH 4/4] Darwin, Ada : Add loader path as a default rpath.

[Iain Sandoe via Gcc-patches]

Allow the Ada runtimes to find GCC runtimes relative to their non-
standard install positions.

gcc/ada/
        * gcc-interface/Makefile.in: Add @loader_path runpaths to the
        libgnat and libgnarl shared library builds.
