Having said that, discussing this has made me realize that in my case it would probably make more sense for me to link against my own shared library anyway to prevent code from being duplicated in both program and library, so my use case is not as likely as I had been originally imagining.

Oh, so you're also providing libraries for other developers.  In that case, you do specify them into the second parameter of fixup_bundle().  If those libraries have additional dependencies, then BundleUtilities could be useful for that.
