aot_create_comp_context: disable small data section

Browse Source 
I observed errors like the following when trying to upgrade our
LLVM from 15 to 19.

```
AOT module load failed: resolve symbol .srodata.cst8 failed
```

The concept itself has been available since LLVM 9.
I don't know what exactly happened to trigger the use of it.

cf. https://reviews.llvm.org/D57493
