    With llvm + mold, linking `libmozsqlite` fails with ```REL-type relocation table is not supported for this target```

```

On discussion at the mold issue tracker, it has been pointed out that LLVM should be generating RELA-type relocations, instead of REL-type relocations on x86_64 (https://github.com/rui314/mold/issues/653#issuecomment-1761300733)
