    Darwin, libffi, testsuite: Ensure we pick up the convenience lib.
    
    For several Darwin linker versions, the link paths are first traversed
    looking for shared libraries, and then again looking for archives.
    
    We want the paths to be searched for both shared and archives in order
    so that we will find the non-shared libffi in the testsuite (otherwise
    the installed version in the system will be found instead).

    libffi/ChangeLog:
    
            * testsuite/lib/libffi.exp: Search for both shared and archive
            in each path in turn.
