This doesn't answer my question of why it couldn't be done the other
way. Why does the makefile need to know it? If it does need to know
it, couldn't it get it out of the control file instead of vice versa?

I'm not convinced that this is actually a requirement, or that doing it
this specific way is a good solution. In particular, keeping the
version number in the system catalogs seems pretty dubious. The common
method for upgrading an already-installed contrib module just involves
dropping in a new .so --- that's not going to change the system
catalogs. It would likely be better to keep the version ID inside the
.so file.
