I think custom_target doesn't work, as this can only be built when doing 
a native build. You have to be able to use the produced bindings module 
to be able to run stubgen.

I expect that the stubs would eventually be something that are committed 
to the repository, and updated when needed.

As we also have the meson 0.57 requirement... Maybe I'll just leave this 
out for now.
