Sadly, no.

Having a standard way to do this would be useful.

I agree that this is a nuisance.

One idea I came up with was to use libabigail:
  https://sourceware.org/libabigail/
to generate an ABI description e.g. via abidw:
  https://sourceware.org/libabigail/manual/abidw.html
which emits an XML file, and then have a pre-canned way of populating a
gcc_jit_context from such an abigail ABI representation.

This code doesn't exist yet, though (but would just need writing once).
