I've built this locally, and checked if references were retained to the
added inputs; it seems ijg-libjpeg is not retained as a reference, which
means it is unused at run time and could be left out (or perhaps it
tries to dynamically load it, in which case the dlopen calls could be
patched, but I doubt so).

--8<---------------cut here---------------start------------->8---
$ guix gc -R /gnu/store/jbdbq8kxy5956wkqg4qrvfdks776gfb1-mscgen-0.20 |
grep ijg-libjpeg
-> no output
--8<---------------cut here---------------end--------------->8---

Could you verify the above, and if my assumption is correct, send a v2
without the added ijg-libjpeg?
