For -fno-pic, if an extern variable is defined in a DSO, a copy relocation will be needed. However, loongarch*-linux does not and will not support copy relocations. Change Driver to default to -fno-direct-access-external-data for LoongArch && non-PIC. Keep Frontend conditions unchanged (-fdirect-access-external-data || -fno-direct-access-external-data && PIC>0 => direct access). Fix #71645
