    Fix T15729 in master
    
    Summary:
    It failed when running ./validate on master
    T15729 is added by me in D5219 recently,
    it failed when GHCi is dynamicly linked:
    
    ```
    Stderr ( T15729 ):
    /bin/ld.gold: error: bss.o: requires unsupported dynamic reloc 11;
    recompile with -fPIC
    collect2: error: ld returned 1 exit status
    `gcc' failed in phase `Linker'. (Exit code: 1)
    ```
    
    Test Plan: Both tests pass now.
