Use @rpath and @loader_path to avoid absolute path
With "-Wl,-rpath,@loader_path/../lib" the linker embeds
@loader_path/../lib as the target binary's rpath.
Here @loader_path means the path of the binary that initiates the
loading.
With "-install_name @rpath/libfoo.dylib " the linker runtime searches
libfoo.dylib in the binary's embeded rpath.
With this change you can call dlopen() without specifying the full path
of the shared library.
