Icenowy Zheng 70dbbc2811 common-user/host/riscv: use tail pseudoinstruction for calling tail ...

The j pseudoinstruction maps to a JAL instruction, which can only handle
a jump to somewhere with a signed 20-bit destination. In case of static
linking and LTO'ing this easily leads to "relocation truncated to fit"
error.

Switch to use tail pseudoinstruction, which is the standard way to
tail-call a function in medium code model (emits AUIPC+JALR).
