The syscall call uses the 'tail' instruction call

If the 'j' command is used here,it cannot always be called.
The 'tail' command is used here, let the compiler decide
which instruction to use,when the call distance is less
than 1M, it will be compiled into 'j' command, and when
the distance is greater than 1M, it will be compiled
into 'aupic' and 'jr' command.
