Upstream uses a massive home-made Makefile which has since the beginning
required massive amounts of patching to make it behave reasonably
(as well as to fix the problems which ostensibly led upstream to
abandoning CMake, and which they immediately re-introduced in their NIH
solution) and which if anything have only got worse since then. One,
optional, reverse dependency in the tree.
Removal on 2023-11-26. Bug #916289.
