I think Andreas's patchset that was recently posted (and is currently
in master-next) takes care of this in a general way, where you don't
have to go and fix every recipe. The unfortunate bit is that meson
does not have a standard flag for enabling/disabling introspection,
but we found a way to deal with this that is as generic as possible.

If you try with master-next, would be good to know.
