After taking a quick look through pgxs.mk, it looks like you might
be able to do something like
override with_llvm := no
in your Makefile before including the PG parts.

Should just prevent the possibility of "inline"-ing your functions
in JIT compilation.

Yeah, the ultimate solution is clearly over on that side. These
last errors you've posted don't seem particularly Postgres-related.
