| ## Prior to D77021 lld would error "relocation R_HEX_GD_PLT_B22_PCREL cannot refer to absolute symbol". |
| ## A PC-relative relocation referencing a non-preemptible absolute symbol (due to STT_TLS) is not representable in -pie/-shared mode. |
| ## For this case we will actually patch the symbol to the external __tls_get_addr which is preemptible. |
