This *very* likely is related to building in a source tree that also contains
a "non-meson" build "in place". The problem is that the meson build picks up
the pg_config.h generated by ./configure in the "normal" build, rather than
the one meson generated itself.
You'd need to execute make distclean or such, or use a separate git checkout.
I forgot about this issue because I only ever build postgres from outside the
source-tree (by invoking configure from a separate directory), so there's
never build products in it. I think at least I need to make the build emit a
warning / error if there's a pg_config.h in the source tree...
This is the part of the jit code that's built regardless of llvm availability
- you'd get the same error in a few other places unrelated to jit.
