Fix the compile errors "R_RISCV_JAL out of rang" when the jump range is greater than 1M memory space between vfork and __set_errno_internal

Browse source 
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 "jr" command, and when
the distance is greater than 1M, it will be compiled
into "aupic" and "jr" command.

Test: make libc
