Updating to clang-19 change the code generation of the JIT stencils. This caused some addresses of symbols to be far away hence it was impossible to reach them out.
Enabling the -fplt restores the behaviour that we had with clang-18.

Interesting!

I assume that the test failure on aarch64 linux is not related to this change? Is this just flaky?

Looks like a fluke... I'm rerunning it.
