In the case of a GPL project including a BSD code, there is not a separate license. Only the copyright holder can change the license. It is just that the BSD license allows you to add additional restrictions. The GPL adds one restriction: whenever you give someone the software, you have to also give them the source code.
GPL also adds the restriction of not adding any additional restrictions, and that's a restriction by itself (I'm not saying that it's good or bad).
It can also be counted as several additional restrictions, depending on the way one reads it.
So if you were going to include Pd-extended in your OS as a whole, you have to treat all the code as GPLv3. list-abs is a library included in Pd-extended. It is released under a BSD license. If you download list-abs by itself and package that, then it is not Pd-extended. So its BSD.
If someone includes Pd-extended as a whole in their OS, and modify BSD externals, while keeping them bundled with the rest of Pd-extended, they don't have to distribute the source to those modifications, despite your claim that Pd-extended has a license « as a whole ». That person doesn't have to take anything apart (debundle) or whatever.
The « as a whole » concept has a more limited applicability than what you seem to be claiming.
