[PD-dev] weak linking on GNU/Linux?

On Mac OS X, Pd-extended "weak" links to the Jack framework, so it doesn't crash if the Jack framework is not there. Is there a way to do this on GNU/Linux? I'd like to compile Pd-extended with Jack support, but right now, it seems to tie the binary to a specific version of Jack if I do that.
