Darwin: Search for both shared and convenience libraries in each path. (#761)

For several Darwin linker versions, the default behaviour is to first traverse
the set of library paths, looking for shared libraries, and then a second time
looking for archives.

This means that if the library is configured --disable-shared the installed
system version /usr/lib/libffi.dylib will be found before the archive under
test.

Using the linker option '-search-paths-first' alters the strategy to search each
path for dylib and then archive before moving on to the next.
