27718 contains a SYMBOL_REF. Relax this constraint during reload, since

27735 pc-relative operands can fit. For example, a pc-relative operand
27736 can be used as a memory source operand for addsi3, but not as a
27737 memory destination.
27738 * hp320.h linux.h m68kv4.h (LEGITIMATE_PIC_OPERAND_P) as in m68k.h.
