When labels-as-values is enabled in a target which doesn't support unaligned address access, 16-bit offset is used to store the relative offset between two opcode labels. But it is a little small and the loader may report "pre-compiled label offset out of range" error. Emitting 32-bit data instead to resolve the issue: emit label address in 32-bit target and emit 32-bit relative offset in 64-bit target.
